Given numbers are 709, 890, 475, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(709, 890) = 631010
GCD(709, 890) = ( 709 x 890 ) / 631010
= 709 / 890
= 709
Step2:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 709, 890, 475, 689 is 1
