Steps to Calculate GCD of 786, 556, 402, 691 using LCM Formula
Given numbers are 786, 556, 402, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 556) = 218508
GCD(786, 556) = ( 786 x 556 ) / 218508
= 786 / 556
= 786
Step2:
LCM(2, 402) = 402
GCD(2, 402) = ( 2 x 402 ) / 402
= 2 / 402
= 2
Step3:
LCM(2, 691) = 1382
GCD(2, 691) = ( 2 x 691 ) / 1382
= 2 / 691
= 2
So, Greatest Common Divisor of 786, 556, 402, 691 is 1
