Steps to Calculate GCD of 38, 57, 56, 65 using LCM Formula
Given numbers are 38, 57, 56, 65
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(38, 57) = 114
GCD(38, 57) = ( 38 x 57 ) / 114
= 38 / 57
= 38
Step2:
LCM(19, 56) = 1064
GCD(19, 56) = ( 19 x 56 ) / 1064
= 19 / 56
= 19
Step3:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
So, Greatest Common Divisor of 38, 57, 56, 65 is 1
