Given numbers are 251, 109, 220, 782

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

Apply this formula for all numbers.

Step1:

LCM(251, 109) = 27359

GCD(251, 109) = ( 251 x 109 ) / 27359

= 251 / 109

= 251

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

So, Greatest Common Divisor of 251, 109, 220, 782 is 1
