Steps to Calculate GCD of 691, 623, 870, 431 using LCM Formula
Given numbers are 691, 623, 870, 431
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 623) = 430493
GCD(691, 623) = ( 691 x 623 ) / 430493
= 691 / 623
= 691
Step2:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
Step3:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
So, Greatest Common Divisor of 691, 623, 870, 431 is 1
