Given numbers are 378, 342, 725, 991

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

Apply this formula for all numbers.

Step1:

LCM(378, 342) = 7182

GCD(378, 342) = ( 378 x 342 ) / 7182

= 378 / 342

= 378

Step2:

LCM(18, 725) = 13050

GCD(18, 725) = ( 18 x 725 ) / 13050

= 18 / 725

= 18

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 378, 342, 725, 991 is 1
