Given numbers are 450, 875, 456, 688
The list of prime factors of all numbers are
Prime factors of 450 are 2 x 3 x 3 x 5 x 5
Prime factors of 875 are 5 x 5 x 5 x 7
Prime factors of 456 are 2 x 2 x 2 x 3 x 19
Prime factors of 688 are 2 x 2 x 2 x 2 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 450, 875, 456, 688
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(450, 875) = 15750
GCD(450, 875) = ( 450 x 875 ) / 15750
= 450 / 875
= 450
Step2:
LCM(25, 456) = 11400
GCD(25, 456) = ( 25 x 456 ) / 11400
= 25 / 456
= 25
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 450, 875, 456, 688 is 1
