Given numbers are 686, 487, 912, 824
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 487) = 334082
GCD(686, 487) = ( 686 x 487 ) / 334082
= 686 / 487
= 686
Step2:
LCM(1, 912) = 912
GCD(1, 912) = ( 1 x 912 ) / 912
= 1 / 912
= 1
Step3:
LCM(1, 824) = 824
GCD(1, 824) = ( 1 x 824 ) / 824
= 1 / 824
= 1
So, Greatest Common Divisor of 686, 487, 912, 824 is 1
