Given numbers are 681, 436, 163, 453
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 436) = 296916
GCD(681, 436) = ( 681 x 436 ) / 296916
= 681 / 436
= 681
Step2:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
Step3:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
So, Greatest Common Divisor of 681, 436, 163, 453 is 1
