Given numbers are 645, 913, 350, 243
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 913) = 588885
GCD(645, 913) = ( 645 x 913 ) / 588885
= 645 / 913
= 645
Step2:
LCM(1, 350) = 350
GCD(1, 350) = ( 1 x 350 ) / 350
= 1 / 350
= 1
Step3:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
So, Greatest Common Divisor of 645, 913, 350, 243 is 1
