Given numbers are 417, 409, 70, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 409) = 170553
GCD(417, 409) = ( 417 x 409 ) / 170553
= 417 / 409
= 417
Step2:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 417, 409, 70, 129 is 1
