Given numbers are 642, 551, 625, 879

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

Apply this formula for all numbers.

Step1:

LCM(642, 551) = 353742

GCD(642, 551) = ( 642 x 551 ) / 353742

= 642 / 551

= 642

Step2:

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

= 1 / 625

= 1

Step3:

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

= 1 / 879

= 1

So, Greatest Common Divisor of 642, 551, 625, 879 is 1
