Prime factors of 991 are 991

Prime factors of 370 are 2 x 5 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 909, 720, 991, 370

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(909, 720) = 72720

GCD(909, 720) = ( 909 x 720 ) / 72720

= 909 / 720

= 909

Step2:

LCM(9, 991) = 8919

GCD(9, 991) = ( 9 x 991 ) / 8919

= 9 / 991

= 9

Step3:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

So, Greatest Common Divisor of 909, 720, 991, 370 is 1
