Given numbers are 120, 910, 456, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 910) = 10920
GCD(120, 910) = ( 120 x 910 ) / 10920
= 120 / 910
= 120
Step2:
LCM(10, 456) = 2280
GCD(10, 456) = ( 10 x 456 ) / 2280
= 10 / 456
= 10
Step3:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
So, Greatest Common Divisor of 120, 910, 456, 620 is 2
