Given numbers are 938, 642, 899, 684

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

Apply this formula for all numbers.

Step1:

LCM(938, 642) = 301098

GCD(938, 642) = ( 938 x 642 ) / 301098

= 938 / 642

= 938

Step2:

LCM(2, 899) = 1798

GCD(2, 899) = ( 2 x 899 ) / 1798

= 2 / 899

= 2

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 938, 642, 899, 684 is 1
