Given numbers are 651, 863, 408, 251

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

Apply this formula for all numbers.

Step1:

LCM(651, 863) = 561813

GCD(651, 863) = ( 651 x 863 ) / 561813

= 651 / 863

= 651

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 651, 863, 408, 251 is 1
