Given numbers are 972, 345, 762, 155

The list of prime factors of all numbers are

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 345 are 3 x 5 x 23

Prime factors of 762 are 2 x 3 x 127

Prime factors of 155 are 5 x 31

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

Given numbers are 972, 345, 762, 155

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

Apply this formula for all numbers.

Step1:

LCM(972, 345) = 111780

GCD(972, 345) = ( 972 x 345 ) / 111780

= 972 / 345

= 972

Step2:

LCM(3, 762) = 762

GCD(3, 762) = ( 3 x 762 ) / 762

= 3 / 762

= 3

Step3:

LCM(3, 155) = 465

GCD(3, 155) = ( 3 x 155 ) / 465

= 3 / 155

= 3

So, Greatest Common Divisor of 972, 345, 762, 155 is 1
