Given numbers are 642, 684, 143, 899

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

Apply this formula for all numbers.

Step1:

LCM(642, 684) = 73188

GCD(642, 684) = ( 642 x 684 ) / 73188

= 642 / 684

= 642

Step2:

LCM(6, 143) = 858

GCD(6, 143) = ( 6 x 143 ) / 858

= 6 / 143

= 6

Step3:

LCM(1, 899) = 899

GCD(1, 899) = ( 1 x 899 ) / 899

= 1 / 899

= 1

So, Greatest Common Divisor of 642, 684, 143, 899 is 1
