Given numbers are 840, 282, 849, 278

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 282 are 2 x 3 x 47

Prime factors of 849 are 3 x 283

Prime factors of 278 are 2 x 139

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

Given numbers are 840, 282, 849, 278

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

Apply this formula for all numbers.

Step1:

LCM(840, 282) = 39480

GCD(840, 282) = ( 840 x 282 ) / 39480

= 840 / 282

= 840

Step2:

LCM(6, 849) = 1698

GCD(6, 849) = ( 6 x 849 ) / 1698

= 6 / 849

= 6

Step3:

LCM(3, 278) = 834

GCD(3, 278) = ( 3 x 278 ) / 834

= 3 / 278

= 3

So, Greatest Common Divisor of 840, 282, 849, 278 is 1
