Given numbers are 443, 438, 613, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(443, 438) = 194034
GCD(443, 438) = ( 443 x 438 ) / 194034
= 443 / 438
= 443
Step2:
LCM(1, 613) = 613
GCD(1, 613) = ( 1 x 613 ) / 613
= 1 / 613
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 443, 438, 613, 645 is 1
