Given numbers are 284, 626, 665, 172

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

Apply this formula for all numbers.

Step1:

LCM(284, 626) = 88892

GCD(284, 626) = ( 284 x 626 ) / 88892

= 284 / 626

= 284

Step2:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 284, 626, 665, 172 is 1
