Given numbers are 680, 921, 653, 913

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

Apply this formula for all numbers.

Step1:

LCM(680, 921) = 626280

GCD(680, 921) = ( 680 x 921 ) / 626280

= 680 / 921

= 680

Step2:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

Step3:

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

= 1 / 913

= 1

So, Greatest Common Divisor of 680, 921, 653, 913 is 1
