Given numbers are 612, 400, 978, 435

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 978 are 2 x 3 x 163

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 612, 400, 978, 435

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

Apply this formula for all numbers.

Step1:

LCM(612, 400) = 61200

GCD(612, 400) = ( 612 x 400 ) / 61200

= 612 / 400

= 612

Step2:

LCM(4, 978) = 1956

GCD(4, 978) = ( 4 x 978 ) / 1956

= 4 / 978

= 4

Step3:

LCM(2, 435) = 870

GCD(2, 435) = ( 2 x 435 ) / 870

= 2 / 435

= 2

So, Greatest Common Divisor of 612, 400, 978, 435 is 1
