Given numbers are 329, 686, 340, 156
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(329, 686) = 32242
GCD(329, 686) = ( 329 x 686 ) / 32242
= 329 / 686
= 329
Step2:
LCM(7, 340) = 2380
GCD(7, 340) = ( 7 x 340 ) / 2380
= 7 / 340
= 7
Step3:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
So, Greatest Common Divisor of 329, 686, 340, 156 is 1
