Given numbers are 491, 500, 621, 308
The list of prime factors of all numbers are
Prime factors of 491 are 491
Prime factors of 500 are 2 x 2 x 5 x 5 x 5
Prime factors of 621 are 3 x 3 x 3 x 23
Prime factors of 308 are 2 x 2 x 7 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 491, 500, 621, 308
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 500) = 245500
GCD(491, 500) = ( 491 x 500 ) / 245500
= 491 / 500
= 491
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
= 1 / 308
= 1
So, Greatest Common Divisor of 491, 500, 621, 308 is 1
