GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 940) = 13160
GCD(280, 940) = ( 280 x 940 ) / 13160
= 280 / 940
= 280
Step2:
LCM(20, 212) = 1060
GCD(20, 212) = ( 20 x 212 ) / 1060
= 20 / 212
= 20
Step3:
LCM(4, 822) = 1644
GCD(4, 822) = ( 4 x 822 ) / 1644
= 4 / 822
= 4
So, Greatest Common Divisor of 280, 940, 212, 822 is 2
