Given numbers are 406, 156, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 156) = 31668
GCD(406, 156) = ( 406 x 156 ) / 31668
= 406 / 156
= 406
Step2:
LCM(2, 705) = 1410
GCD(2, 705) = ( 2 x 705 ) / 1410
= 2 / 705
= 2
So, Greatest Common Divisor of 406, 156, 705 is 1
