Given numbers are 155, 781, 570, 702

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 781 are 11 x 71

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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

Given numbers are 155, 781, 570, 702

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

Apply this formula for all numbers.

Step1:

LCM(155, 781) = 121055

GCD(155, 781) = ( 155 x 781 ) / 121055

= 155 / 781

= 155

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

So, Greatest Common Divisor of 155, 781, 570, 702 is 1
