Given numbers are 680, 128, 651, 898

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

Apply this formula for all numbers.

Step1:

LCM(680, 128) = 10880

GCD(680, 128) = ( 680 x 128 ) / 10880

= 680 / 128

= 680

Step2:

LCM(8, 651) = 5208

GCD(8, 651) = ( 8 x 651 ) / 5208

= 8 / 651

= 8

Step3:

LCM(1, 898) = 898

GCD(1, 898) = ( 1 x 898 ) / 898

= 1 / 898

= 1

So, Greatest Common Divisor of 680, 128, 651, 898 is 1
