Given numbers are 664, 816, 172, 125

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

Apply this formula for all numbers.

Step1:

LCM(664, 816) = 67728

GCD(664, 816) = ( 664 x 816 ) / 67728

= 664 / 816

= 664

Step2:

LCM(8, 172) = 344

GCD(8, 172) = ( 8 x 172 ) / 344

= 8 / 172

= 8

Step3:

LCM(4, 125) = 500

GCD(4, 125) = ( 4 x 125 ) / 500

= 4 / 125

= 4

So, Greatest Common Divisor of 664, 816, 172, 125 is 1
