Given numbers are 968, 639, 280, 454

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

Apply this formula for all numbers.

Step1:

LCM(968, 639) = 618552

GCD(968, 639) = ( 968 x 639 ) / 618552

= 968 / 639

= 968

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 968, 639, 280, 454 is 1
