Steps to Calculate GCD of 761, 921, 84, 100 using LCM Formula
Given numbers are 761, 921, 84, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(761, 921) = 700881
GCD(761, 921) = ( 761 x 921 ) / 700881
= 761 / 921
= 761
Step2:
LCM(1, 84) = 84
GCD(1, 84) = ( 1 x 84 ) / 84
= 1 / 84
= 1
Step3:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
So, Greatest Common Divisor of 761, 921, 84, 100 is 1
