Given numbers are 700, 990, 691, 644
The list of prime factors of all numbers are
Prime factors of 700 are 2 x 2 x 5 x 5 x 7
Prime factors of 990 are 2 x 3 x 3 x 5 x 11
Prime factors of 691 are 691
Prime factors of 644 are 2 x 2 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 700, 990, 691, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(700, 990) = 69300
GCD(700, 990) = ( 700 x 990 ) / 69300
= 700 / 990
= 700
Step2:
LCM(10, 691) = 6910
GCD(10, 691) = ( 10 x 691 ) / 6910
= 10 / 691
= 10
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 700, 990, 691, 644 is 1
