Given numbers are 720, 211, 648, 628
The list of prime factors of all numbers are
Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 211 are 211
Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3
Prime factors of 628 are 2 x 2 x 157
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 720, 211, 648, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 211) = 151920
GCD(720, 211) = ( 720 x 211 ) / 151920
= 720 / 211
= 720
Step2:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 720, 211, 648, 628 is 1
