Given numbers are 800, 660, 497, 129
The list of prime factors of all numbers are
Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 497 are 7 x 71
Prime factors of 129 are 3 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 800, 660, 497, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(800, 660) = 26400
GCD(800, 660) = ( 800 x 660 ) / 26400
= 800 / 660
= 800
Step2:
LCM(20, 497) = 9940
GCD(20, 497) = ( 20 x 497 ) / 9940
= 20 / 497
= 20
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 800, 660, 497, 129 is 1
