Given numbers are 645, 685, 793, 301
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 685) = 88365
GCD(645, 685) = ( 645 x 685 ) / 88365
= 645 / 685
= 645
Step2:
LCM(5, 793) = 3965
GCD(5, 793) = ( 5 x 793 ) / 3965
= 5 / 793
= 5
Step3:
LCM(1, 301) = 301
GCD(1, 301) = ( 1 x 301 ) / 301
= 1 / 301
= 1
So, Greatest Common Divisor of 645, 685, 793, 301 is 1
