Given numbers are 695, 905, 386, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(695, 905) = 125795
GCD(695, 905) = ( 695 x 905 ) / 125795
= 695 / 905
= 695
Step2:
LCM(5, 386) = 1930
GCD(5, 386) = ( 5 x 386 ) / 1930
= 5 / 386
= 5
Step3:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
So, Greatest Common Divisor of 695, 905, 386, 143 is 1
