Given numbers are 240, 521, 684, 855
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 521) = 125040
GCD(240, 521) = ( 240 x 521 ) / 125040
= 240 / 521
= 240
Step2:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 240, 521, 684, 855 is 1
