Given numbers are 990, 438, 343, 962

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

Apply this formula for all numbers.

Step1:

LCM(990, 438) = 72270

GCD(990, 438) = ( 990 x 438 ) / 72270

= 990 / 438

= 990

Step2:

LCM(6, 343) = 2058

GCD(6, 343) = ( 6 x 343 ) / 2058

= 6 / 343

= 6

Step3:

LCM(1, 962) = 962

GCD(1, 962) = ( 1 x 962 ) / 962

= 1 / 962

= 1

So, Greatest Common Divisor of 990, 438, 343, 962 is 1
