Given numbers are 620, 837, 921, 887

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

Apply this formula for all numbers.

Step1:

LCM(620, 837) = 16740

GCD(620, 837) = ( 620 x 837 ) / 16740

= 620 / 837

= 620

Step2:

LCM(31, 921) = 28551

GCD(31, 921) = ( 31 x 921 ) / 28551

= 31 / 921

= 31

Step3:

LCM(1, 887) = 887

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

= 1 / 887

= 1

So, Greatest Common Divisor of 620, 837, 921, 887 is 1
