Given numbers are 409, 648, 122, 134
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 648) = 265032
GCD(409, 648) = ( 409 x 648 ) / 265032
= 409 / 648
= 409
Step2:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
Step3:
LCM(1, 134) = 134
GCD(1, 134) = ( 1 x 134 ) / 134
= 1 / 134
= 1
So, Greatest Common Divisor of 409, 648, 122, 134 is 1
