Given numbers are 245, 531, 660, 492
The list of prime factors of all numbers are
Prime factors of 245 are 5 x 7 x 7
Prime factors of 531 are 3 x 3 x 59
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 492 are 2 x 2 x 3 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 245, 531, 660, 492
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 531) = 130095
GCD(245, 531) = ( 245 x 531 ) / 130095
= 245 / 531
= 245
Step2:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
Step3:
LCM(1, 492) = 492
GCD(1, 492) = ( 1 x 492 ) / 492
= 1 / 492
= 1
So, Greatest Common Divisor of 245, 531, 660, 492 is 1
