Given numbers are 280, 636, 436, 664

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

Apply this formula for all numbers.

Step1:

LCM(280, 636) = 44520

GCD(280, 636) = ( 280 x 636 ) / 44520

= 280 / 636

= 280

Step2:

LCM(4, 436) = 436

GCD(4, 436) = ( 4 x 436 ) / 436

= 4 / 436

= 4

Step3:

LCM(4, 664) = 664

GCD(4, 664) = ( 4 x 664 ) / 664

= 4 / 664

= 4

So, Greatest Common Divisor of 280, 636, 436, 664 is 4
