Given numbers are 240, 170, 56
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 170) = 4080
GCD(240, 170) = ( 240 x 170 ) / 4080
= 240 / 170
= 240
Step2:
LCM(10, 56) = 280
GCD(10, 56) = ( 10 x 56 ) / 280
= 10 / 56
= 10
So, Greatest Common Divisor of 240, 170, 56 is 2
