Given numbers are 215, 870, 399, 914
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 870) = 37410
GCD(215, 870) = ( 215 x 870 ) / 37410
= 215 / 870
= 215
Step2:
LCM(5, 399) = 1995
GCD(5, 399) = ( 5 x 399 ) / 1995
= 5 / 399
= 5
Step3:
LCM(1, 914) = 914
GCD(1, 914) = ( 1 x 914 ) / 914
= 1 / 914
= 1
So, Greatest Common Divisor of 215, 870, 399, 914 is 1
