Given numbers are 243, 818, 643, 602
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 818) = 198774
GCD(243, 818) = ( 243 x 818 ) / 198774
= 243 / 818
= 243
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
= 1 / 602
= 1
So, Greatest Common Divisor of 243, 818, 643, 602 is 1
