Given numbers are 420, 376, 741, 991

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

Apply this formula for all numbers.

Step1:

LCM(420, 376) = 39480

GCD(420, 376) = ( 420 x 376 ) / 39480

= 420 / 376

= 420

Step2:

LCM(4, 741) = 2964

GCD(4, 741) = ( 4 x 741 ) / 2964

= 4 / 741

= 4

Step3:

LCM(1, 991) = 991

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

= 1 / 991

= 1

So, Greatest Common Divisor of 420, 376, 741, 991 is 1
