Given numbers are 660, 630, 619, 217
The list of prime factors of all numbers are
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
Prime factors of 619 are 619
Prime factors of 217 are 7 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 660, 630, 619, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 630) = 13860
GCD(660, 630) = ( 660 x 630 ) / 13860
= 660 / 630
= 660
Step2:
LCM(30, 619) = 18570
GCD(30, 619) = ( 30 x 619 ) / 18570
= 30 / 619
= 30
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 660, 630, 619, 217 is 1
