Given numbers are 280, 956, 913, 686

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

Apply this formula for all numbers.

Step1:

LCM(280, 956) = 66920

GCD(280, 956) = ( 280 x 956 ) / 66920

= 280 / 956

= 280

Step2:

LCM(4, 913) = 3652

GCD(4, 913) = ( 4 x 913 ) / 3652

= 4 / 913

= 4

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 280, 956, 913, 686 is 1
