HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 708, 453, 18 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 708, 453, 18 is 3 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 708, 453, 18 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 708, 453, 18 is 3.

HCF(708, 453, 18) = 3

Highest common factor (HCF) of 708, 453, 18 is 3.

Highest Common Factor of 708,453,18 using Euclid's algorithm

Highest Common Factor of 708,453,18 is 3

Step 1: Since 708 > 453, we apply the division lemma to 708 and 453, to get

708 = 453 x 1 + 255

Step 2: Since the reminder 453 ≠ 0, we apply division lemma to 255 and 453, to get

453 = 255 x 1 + 198

Step 3: We consider the new divisor 255 and the new remainder 198, and apply the division lemma to get

255 = 198 x 1 + 57

We consider the new divisor 198 and the new remainder 57,and apply the division lemma to get

198 = 57 x 3 + 27

We consider the new divisor 57 and the new remainder 27,and apply the division lemma to get

57 = 27 x 2 + 3

We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get

27 = 3 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 708 and 453 is 3

Notice that 3 = HCF(27,3) = HCF(57,27) = HCF(198,57) = HCF(255,198) = HCF(453,255) = HCF(708,453) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 18 > 3, we apply the division lemma to 18 and 3, to get

18 = 3 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 18 is 3

Notice that 3 = HCF(18,3) .
