The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 640, 620, 446, 877

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

Apply this formula for all numbers.

Step1:

LCM(640, 620) = 19840

GCD(640, 620) = ( 640 x 620 ) / 19840

= 640 / 620

= 640

Step2:

LCM(20, 446) = 4460

GCD(20, 446) = ( 20 x 446 ) / 4460

= 20 / 446

= 20

Step3:

LCM(2, 877) = 1754

GCD(2, 877) = ( 2 x 877 ) / 1754

= 2 / 877

= 2

So, Greatest Common Divisor of 640, 620, 446, 877 is 1
