Given numbers are 392, 272, 190, 987

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

Apply this formula for all numbers.

Step1:

LCM(392, 272) = 13328

GCD(392, 272) = ( 392 x 272 ) / 13328

= 392 / 272

= 392

Step2:

LCM(8, 190) = 760

GCD(8, 190) = ( 8 x 190 ) / 760

= 8 / 190

= 8

Step3:

LCM(2, 987) = 1974

GCD(2, 987) = ( 2 x 987 ) / 1974

= 2 / 987

= 2

So, Greatest Common Divisor of 392, 272, 190, 987 is 1
