Given numbers are 640, 685, 147, 879

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

Apply this formula for all numbers.

Step1:

LCM(640, 685) = 87680

GCD(640, 685) = ( 640 x 685 ) / 87680

= 640 / 685

= 640

Step2:

LCM(5, 147) = 735

GCD(5, 147) = ( 5 x 147 ) / 735

= 5 / 147

= 5

Step3:

LCM(1, 879) = 879

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

= 1 / 879

= 1

So, Greatest Common Divisor of 640, 685, 147, 879 is 1
