Given numbers are 243, 840, 353, 506
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 840) = 68040
GCD(243, 840) = ( 243 x 840 ) / 68040
= 243 / 840
= 243
Step2:
LCM(3, 353) = 1059
GCD(3, 353) = ( 3 x 353 ) / 1059
= 3 / 353
= 3
Step3:
LCM(1, 506) = 506
GCD(1, 506) = ( 1 x 506 ) / 506
= 1 / 506
= 1
So, Greatest Common Divisor of 243, 840, 353, 506 is 1
