Given numbers are 660, 210, 286, 497
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 210 are 2 x 3 x 5 x 7
Prime factors of 286 are 2 x 11 x 13
Prime factors of 497 are 7 x 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 660, 210, 286, 497
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 210) = 4620
GCD(660, 210) = ( 660 x 210 ) / 4620
= 660 / 210
= 660
Step2:
LCM(30, 286) = 4290
GCD(30, 286) = ( 30 x 286 ) / 4290
= 30 / 286
= 30
Step3:
LCM(2, 497) = 994
GCD(2, 497) = ( 2 x 497 ) / 994
= 2 / 497
= 2
So, Greatest Common Divisor of 660, 210, 286, 497 is 1
