Given numbers are 406, 815, 705, 946
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 815) = 330890
GCD(406, 815) = ( 406 x 815 ) / 330890
= 406 / 815
= 406
Step2:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
Step3:
LCM(1, 946) = 946
GCD(1, 946) = ( 1 x 946 ) / 946
= 1 / 946
= 1
So, Greatest Common Divisor of 406, 815, 705, 946 is 1
