Given numbers are 420, 650, 128, 199
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 650) = 27300
GCD(420, 650) = ( 420 x 650 ) / 27300
= 420 / 650
= 420
Step2:
LCM(10, 128) = 640
GCD(10, 128) = ( 10 x 128 ) / 640
= 10 / 128
= 10
Step3:
LCM(2, 199) = 398
GCD(2, 199) = ( 2 x 199 ) / 398
= 2 / 199
= 2
So, Greatest Common Divisor of 420, 650, 128, 199 is 1
