Given numbers are 940, 990, 390, 872
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(940, 990) = 93060
GCD(940, 990) = ( 940 x 990 ) / 93060
= 940 / 990
= 940
Step2:
LCM(10, 390) = 390
GCD(10, 390) = ( 10 x 390 ) / 390
= 10 / 390
= 10
Step3:
LCM(10, 872) = 4360
GCD(10, 872) = ( 10 x 872 ) / 4360
= 10 / 872
= 10
So, Greatest Common Divisor of 940, 990, 390, 872 is 2
