Given numbers are 900, 149, 644, 663
The list of prime factors of all numbers are
Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5
Prime factors of 149 are 149
Prime factors of 644 are 2 x 2 x 7 x 23
Prime factors of 663 are 3 x 13 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 900, 149, 644, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(900, 149) = 134100
GCD(900, 149) = ( 900 x 149 ) / 134100
= 900 / 149
= 900
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 900, 149, 644, 663 is 1
