Given numbers are 160, 686, 219, 430
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(160, 686) = 54880
GCD(160, 686) = ( 160 x 686 ) / 54880
= 160 / 686
= 160
Step2:
LCM(2, 219) = 438
GCD(2, 219) = ( 2 x 219 ) / 438
= 2 / 219
= 2
Step3:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
So, Greatest Common Divisor of 160, 686, 219, 430 is 1
