Prime factors of 645 are 3 x 5 x 43
Prime factors of 675 are 3 x 3 x 3 x 5 x 5
Prime factors of 481 are 13 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 780, 645, 675, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 645) = 33540
GCD(780, 645) = ( 780 x 645 ) / 33540
= 780 / 645
= 780
Step2:
LCM(15, 675) = 675
GCD(15, 675) = ( 15 x 675 ) / 675
= 15 / 675
= 15
Step3:
LCM(15, 481) = 7215
GCD(15, 481) = ( 15 x 481 ) / 7215
= 15 / 481
= 15
So, Greatest Common Divisor of 780, 645, 675, 481 is 1
