Given numbers are 404, 430, 940, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(404, 430) = 86860
GCD(404, 430) = ( 404 x 430 ) / 86860
= 404 / 430
= 404
Step2:
LCM(2, 940) = 940
GCD(2, 940) = ( 2 x 940 ) / 940
= 2 / 940
= 2
Step3:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
So, Greatest Common Divisor of 404, 430, 940, 645 is 1
