Steps to Calculate GCD of 691, 206, 970, 453 using LCM Formula
Given numbers are 691, 206, 970, 453
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 206) = 142346
GCD(691, 206) = ( 691 x 206 ) / 142346
= 691 / 206
= 691
Step2:
LCM(1, 970) = 970
GCD(1, 970) = ( 1 x 970 ) / 970
= 1 / 970
= 1
Step3:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
So, Greatest Common Divisor of 691, 206, 970, 453 is 1
