Steps to Calculate GCD of 63, 18, 38, 56 using LCM Formula
Given numbers are 63, 18, 38, 56
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(63, 18) = 126
GCD(63, 18) = ( 63 x 18 ) / 126
= 63 / 18
= 63
Step2:
LCM(9, 38) = 342
GCD(9, 38) = ( 9 x 38 ) / 342
= 9 / 38
= 9
Step3:
LCM(1, 56) = 56
GCD(1, 56) = ( 1 x 56 ) / 56
= 1 / 56
= 1
So, Greatest Common Divisor of 63, 18, 38, 56 is 1
