Given numbers are 491, 980, 740, 654

The list of prime factors of all numbers are

Prime factors of 491 are 491

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 491, 980, 740, 654

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

Apply this formula for all numbers.

Step1:

LCM(491, 980) = 481180

GCD(491, 980) = ( 491 x 980 ) / 481180

= 491 / 980

= 491

Step2:

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

= 1 / 740

= 1

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 491, 980, 740, 654 is 1
