Given numbers are 374, 781, 487, 489

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

Apply this formula for all numbers.

Step1:

LCM(374, 781) = 26554

GCD(374, 781) = ( 374 x 781 ) / 26554

= 374 / 781

= 374

Step2:

LCM(11, 487) = 5357

GCD(11, 487) = ( 11 x 487 ) / 5357

= 11 / 487

= 11

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 374, 781, 487, 489 is 1
