Given numbers are 930, 290, 142, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(930, 290) = 26970
GCD(930, 290) = ( 930 x 290 ) / 26970
= 930 / 290
= 930
Step2:
LCM(10, 142) = 710
GCD(10, 142) = ( 10 x 142 ) / 710
= 10 / 142
= 10
Step3:
LCM(2, 689) = 1378
GCD(2, 689) = ( 2 x 689 ) / 1378
= 2 / 689
= 2
So, Greatest Common Divisor of 930, 290, 142, 689 is 1
