Prime factors of 364 are 2 x 2 x 7 x 13
Prime factors of 442 are 2 x 13 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 815, 680, 364, 442
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 680) = 110840
GCD(815, 680) = ( 815 x 680 ) / 110840
= 815 / 680
= 815
Step2:
LCM(5, 364) = 1820
GCD(5, 364) = ( 5 x 364 ) / 1820
= 5 / 364
= 5
Step3:
LCM(1, 442) = 442
GCD(1, 442) = ( 1 x 442 ) / 442
= 1 / 442
= 1
So, Greatest Common Divisor of 815, 680, 364, 442 is 1
