Given numbers are 170, 685, 830, 149
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 685) = 23290
GCD(170, 685) = ( 170 x 685 ) / 23290
= 170 / 685
= 170
Step2:
LCM(5, 830) = 830
GCD(5, 830) = ( 5 x 830 ) / 830
= 5 / 830
= 5
Step3:
LCM(5, 149) = 745
GCD(5, 149) = ( 5 x 149 ) / 745
= 5 / 149
= 5
So, Greatest Common Divisor of 170, 685, 830, 149 is 1
