Given numbers are 444, 164, 343, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(444, 164) = 18204
GCD(444, 164) = ( 444 x 164 ) / 18204
= 444 / 164
= 444
Step2:
LCM(4, 343) = 1372
GCD(4, 343) = ( 4 x 343 ) / 1372
= 4 / 343
= 4
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 444, 164, 343, 640 is 1
