HCF of Two Numbers by Prime Factorisation & Division Method
WebLCM (a,b) = (a × b) ÷ HCF(a,b) This LCM formula means that the LCM of two numbers 'a' and 'b' is equal to the product of the 2 numbers divided by the HCF of the 2 numbers. Let us understand this using the following example. Example: Find the LCM of 12 and 21 if their HCF is 3. Solution: The given numbers are 12 and 21, the HCF of the numbers = 3 WebTo get HCF, find the product common prime factors of all the three numbers 28, 42 and 56. HCF of (32, 48, 64) = 2 x 2 x 2 x 2 = 16 Find the LCM of 32, 48 and 64. Use ladder division and decompose 28, 42 and 56 into prime … fish dumplings recipe

WebJan 31, 2024 · Solution: Use the same remainder formula and we get answer as 4. Ques 3: Find the greatest number which on dividing 1657 and 2037, leaves a remainder of 6 and 5 respectively. Solution: Use same remainder for each formula and we get 127. Ques 4: The sum of two numbers is 216 and their HCF is 27. WebA much more efficient method to find the H.C.F. is the Euclidean algorithm. Euclidean algorithm This algorithm is based on the fact that H.C.F. of two numbers divides their difference as well. In this algorithm, we divide the greater by smaller and take the remainder. Now, divide the smaller by this remainder. Repeat until the remainder is 0.
