Steps to Calculate GCD of 771, 545, 123, 679 using LCM Formula
Given numbers are 771, 545, 123, 679
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 545) = 420195
GCD(771, 545) = ( 771 x 545 ) / 420195
= 771 / 545
= 771
Step2:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
Step3:
LCM(1, 679) = 679
GCD(1, 679) = ( 1 x 679 ) / 679
= 1 / 679
= 1
So, Greatest Common Divisor of 771, 545, 123, 679 is 1
