Given numbers are 861, 581, 748, 657

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

Apply this formula for all numbers.

Step1:

LCM(861, 581) = 71463

GCD(861, 581) = ( 861 x 581 ) / 71463

= 861 / 581

= 861

Step2:

LCM(7, 748) = 5236

GCD(7, 748) = ( 7 x 748 ) / 5236

= 7 / 748

= 7

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 861, 581, 748, 657 is 1
