Given numbers are 280, 492, 659, 649

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

Apply this formula for all numbers.

Step1:

LCM(280, 492) = 34440

GCD(280, 492) = ( 280 x 492 ) / 34440

= 280 / 492

= 280

Step2:

LCM(4, 659) = 2636

GCD(4, 659) = ( 4 x 659 ) / 2636

= 4 / 659

= 4

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 280, 492, 659, 649 is 1
