Given numbers are 620, 310, 120, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 310) = 620
GCD(620, 310) = ( 620 x 310 ) / 620
= 620 / 310
= 620
Step2:
LCM(310, 120) = 3720
GCD(310, 120) = ( 310 x 120 ) / 3720
= 310 / 120
= 310
Step3:
LCM(10, 787) = 7870
GCD(10, 787) = ( 10 x 787 ) / 7870
= 10 / 787
= 10
So, Greatest Common Divisor of 620, 310, 120, 787 is 1
