Given numbers are 621, 672, 144, 620
The list of prime factors of all numbers are
Prime factors of 621 are 3 x 3 x 3 x 23
Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7
Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3
Prime factors of 620 are 2 x 2 x 5 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 621, 672, 144, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 672) = 139104
GCD(621, 672) = ( 621 x 672 ) / 139104
= 621 / 672
= 621
Step2:
LCM(3, 144) = 144
GCD(3, 144) = ( 3 x 144 ) / 144
= 3 / 144
= 3
Step3:
LCM(3, 620) = 1860
GCD(3, 620) = ( 3 x 620 ) / 1860
= 3 / 620
= 3
So, Greatest Common Divisor of 621, 672, 144, 620 is 1
