Given numbers are 390, 642, 46, 885

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

Apply this formula for all numbers.

Step1:

LCM(390, 642) = 41730

GCD(390, 642) = ( 390 x 642 ) / 41730

= 390 / 642

= 390

Step2:

LCM(6, 46) = 138

GCD(6, 46) = ( 6 x 46 ) / 138

= 6 / 46

= 6

Step3:

LCM(2, 885) = 1770

GCD(2, 885) = ( 2 x 885 ) / 1770

= 2 / 885

= 2

So, Greatest Common Divisor of 390, 642, 46, 885 is 1
