Steps to Calculate GCD of 990, 140, 338, 865 using LCM Formula

Given numbers are 990, 140, 338, 865

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

Apply this formula for all numbers.

Step1:

LCM(990, 140) = 13860

GCD(990, 140) = ( 990 x 140 ) / 13860

= 990 / 140

= 990


Step2:

LCM(10, 338) = 1690

GCD(10, 338) = ( 10 x 338 ) / 1690

= 10 / 338

= 10


Step3:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2


So, Greatest Common Divisor of 990, 140, 338, 865 is 1
