Given numbers are 826, 612, 171, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(826, 612) = 252756
GCD(826, 612) = ( 826 x 612 ) / 252756
= 826 / 612
= 826
Step2:
LCM(2, 171) = 342
GCD(2, 171) = ( 2 x 171 ) / 342
= 2 / 171
= 2
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 826, 612, 171, 686 is 1
