Given numbers are 287, 655, 243, 834
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 655) = 187985
GCD(287, 655) = ( 287 x 655 ) / 187985
= 287 / 655
= 287
Step2:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
Step3:
LCM(1, 834) = 834
GCD(1, 834) = ( 1 x 834 ) / 834
= 1 / 834
= 1
So, Greatest Common Divisor of 287, 655, 243, 834 is 1
