Given numbers are 625, 971, 28, 643

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

Apply this formula for all numbers.

Step1:

LCM(625, 971) = 606875

GCD(625, 971) = ( 625 x 971 ) / 606875

= 625 / 971

= 625

Step2:

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

= 1 / 28

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 625, 971, 28, 643 is 1
