Given numbers are 143, 617, 650, 980

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 617 are 617

Prime factors of 650 are 2 x 5 x 5 x 13

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

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

Given numbers are 143, 617, 650, 980

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

Apply this formula for all numbers.

Step1:

LCM(143, 617) = 88231

GCD(143, 617) = ( 143 x 617 ) / 88231

= 143 / 617

= 143

Step2:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 143, 617, 650, 980 is 1
