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

Given numbers are 638, 360, 989, 887

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

Apply this formula for all numbers.

Step1:

LCM(638, 360) = 114840

GCD(638, 360) = ( 638 x 360 ) / 114840

= 638 / 360

= 638

Step2:

LCM(2, 989) = 1978

GCD(2, 989) = ( 2 x 989 ) / 1978

= 2 / 989

= 2

Step3:

LCM(1, 887) = 887

GCD(1, 887) = ( 1 x 887 ) / 887

= 1 / 887

= 1

So, Greatest Common Divisor of 638, 360, 989, 887 is 1
