Steps to Calculate GCD of 56, 42, 19, 97 using LCM Formula
Given numbers are 56, 42, 19, 97
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(56, 42) = 168
GCD(56, 42) = ( 56 x 42 ) / 168
= 56 / 42
= 56
Step2:
LCM(14, 19) = 266
GCD(14, 19) = ( 14 x 19 ) / 266
= 14 / 19
= 14
Step3:
LCM(1, 97) = 97
GCD(1, 97) = ( 1 x 97 ) / 97
= 1 / 97
= 1
So, Greatest Common Divisor of 56, 42, 19, 97 is 1
