Given numbers are 249, 975, 877, 721

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

Apply this formula for all numbers.

Step1:

LCM(249, 975) = 80925

GCD(249, 975) = ( 249 x 975 ) / 80925

= 249 / 975

= 249

Step2:

LCM(3, 877) = 2631

GCD(3, 877) = ( 3 x 877 ) / 2631

= 3 / 877

= 3

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 249, 975, 877, 721 is 1
