Steps to Calculate GCD of 638, 831, 807, 742 using LCM Formula

Given numbers are 638, 831, 807, 742

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(638, 831) = 530178

GCD(638, 831) = ( 638 x 831 ) / 530178

= 638 / 831

= 638


Step2:

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

= 1 / 807

= 1


Step3:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1


So, Greatest Common Divisor of 638, 831, 807, 742 is 1
