Given numbers are 390, 862, 172, 893

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

Apply this formula for all numbers.

Step1:

LCM(390, 862) = 168090

GCD(390, 862) = ( 390 x 862 ) / 168090

= 390 / 862

= 390

Step2:

LCM(2, 172) = 172

GCD(2, 172) = ( 2 x 172 ) / 172

= 2 / 172

= 2

Step3:

LCM(2, 893) = 1786

GCD(2, 893) = ( 2 x 893 ) / 1786

= 2 / 893

= 2

So, Greatest Common Divisor of 390, 862, 172, 893 is 1
