Given numbers are 890, 970, 699, 856
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 970) = 86330
GCD(890, 970) = ( 890 x 970 ) / 86330
= 890 / 970
= 890
Step2:
LCM(10, 699) = 6990
GCD(10, 699) = ( 10 x 699 ) / 6990
= 10 / 699
= 10
Step3:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
So, Greatest Common Divisor of 890, 970, 699, 856 is 1
