Given numbers are 380, 649, 645, 943
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 649) = 246620
GCD(380, 649) = ( 380 x 649 ) / 246620
= 380 / 649
= 380
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 943) = 943
GCD(1, 943) = ( 1 x 943 ) / 943
= 1 / 943
= 1
So, Greatest Common Divisor of 380, 649, 645, 943 is 1
