Given numbers are 685, 218, 826, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 218) = 149330
GCD(685, 218) = ( 685 x 218 ) / 149330
= 685 / 218
= 685
Step2:
LCM(1, 826) = 826
GCD(1, 826) = ( 1 x 826 ) / 826
= 1 / 826
= 1
Step3:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
So, Greatest Common Divisor of 685, 218, 826, 307 is 1
