Given numbers are 147, 144, 890, 636

The list of prime factors of all numbers are

Prime factors of 147 are 3 x 7 x 7

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 890 are 2 x 5 x 89

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 147, 144, 890, 636

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

Apply this formula for all numbers.

Step1:

LCM(147, 144) = 7056

GCD(147, 144) = ( 147 x 144 ) / 7056

= 147 / 144

= 147

Step2:

LCM(3, 890) = 2670

GCD(3, 890) = ( 3 x 890 ) / 2670

= 3 / 890

= 3

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 147, 144, 890, 636 is 1
