Given numbers are 660, 374, 192, 638

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

Apply this formula for all numbers.

Step1:

LCM(660, 374) = 11220

GCD(660, 374) = ( 660 x 374 ) / 11220

= 660 / 374

= 660

Step2:

LCM(22, 192) = 2112

GCD(22, 192) = ( 22 x 192 ) / 2112

= 22 / 192

= 22

Step3:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

So, Greatest Common Divisor of 660, 374, 192, 638 is 2
