Given numbers are 618, 553, 620, 126

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 553 are 7 x 79

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 618, 553, 620, 126

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

Apply this formula for all numbers.

Step1:

LCM(618, 553) = 341754

GCD(618, 553) = ( 618 x 553 ) / 341754

= 618 / 553

= 618

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 618, 553, 620, 126 is 1
