Given numbers are 947, 400, 135, 660

The list of prime factors of all numbers are

Prime factors of 947 are 947

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

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 947, 400, 135, 660

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

Apply this formula for all numbers.

Step1:

LCM(947, 400) = 378800

GCD(947, 400) = ( 947 x 400 ) / 378800

= 947 / 400

= 947

Step2:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 947, 400, 135, 660 is 1
