Given numbers are 438, 345, 794, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 345) = 50370
GCD(438, 345) = ( 438 x 345 ) / 50370
= 438 / 345
= 438
Step2:
LCM(3, 794) = 2382
GCD(3, 794) = ( 3 x 794 ) / 2382
= 3 / 794
= 3
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 438, 345, 794, 163 is 1
