GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(470, 492) = 115620
GCD(470, 492) = ( 470 x 492 ) / 115620
= 470 / 492
= 470
Step2:
LCM(2, 194) = 194
GCD(2, 194) = ( 2 x 194 ) / 194
= 2 / 194
= 2
Step3:
LCM(2, 640) = 640
GCD(2, 640) = ( 2 x 640 ) / 640
= 2 / 640
= 2
So, Greatest Common Divisor of 470, 492, 194, 640 is 2
