Given numbers are 280, 974, 63, 357

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

Apply this formula for all numbers.

Step1:

LCM(280, 974) = 136360

GCD(280, 974) = ( 280 x 974 ) / 136360

= 280 / 974

= 280

Step2:

LCM(2, 63) = 126

GCD(2, 63) = ( 2 x 63 ) / 126

= 2 / 63

= 2

Step3:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

So, Greatest Common Divisor of 280, 974, 63, 357 is 1
