Given numbers are 709, 170, 818, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(709, 170) = 120530
GCD(709, 170) = ( 709 x 170 ) / 120530
= 709 / 170
= 709
Step2:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 709, 170, 818, 215 is 1
