The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 920, 980, 293, 647

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

Apply this formula for all numbers.

Step1:

LCM(920, 980) = 45080

GCD(920, 980) = ( 920 x 980 ) / 45080

= 920 / 980

= 920

Step2:

LCM(20, 293) = 5860

GCD(20, 293) = ( 20 x 293 ) / 5860

= 20 / 293

= 20

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 920, 980, 293, 647 is 1
