Given numbers are 278, 784, 981, 751

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

Apply this formula for all numbers.

Step1:

LCM(278, 784) = 108976

GCD(278, 784) = ( 278 x 784 ) / 108976

= 278 / 784

= 278

Step2:

LCM(2, 981) = 1962

GCD(2, 981) = ( 2 x 981 ) / 1962

= 2 / 981

= 2

Step3:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1

So, Greatest Common Divisor of 278, 784, 981, 751 is 1
