Given numbers are 543, 858, 987, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(543, 858) = 155298
GCD(543, 858) = ( 543 x 858 ) / 155298
= 543 / 858
= 543
Step2:
LCM(3, 987) = 987
GCD(3, 987) = ( 3 x 987 ) / 987
= 3 / 987
= 3
Step3:
LCM(3, 247) = 741
GCD(3, 247) = ( 3 x 247 ) / 741
= 3 / 247
= 3
So, Greatest Common Divisor of 543, 858, 987, 247 is 1
