Given numbers are 850, 420, 470, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(850, 420) = 35700
GCD(850, 420) = ( 850 x 420 ) / 35700
= 850 / 420
= 850
Step2:
LCM(10, 470) = 470
GCD(10, 470) = ( 10 x 470 ) / 470
= 10 / 470
= 10
Step3:
LCM(10, 393) = 3930
GCD(10, 393) = ( 10 x 393 ) / 3930
= 10 / 393
= 10
So, Greatest Common Divisor of 850, 420, 470, 393 is 1
