HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 253, 676, 33 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 253, 676, 33 is 1 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 253, 676, 33 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 253, 676, 33 is 1.

HCF(253, 676, 33) = 1

Highest Common Factor of 253,676,33 using Euclid's algorithm

Highest Common Factor of 253,676,33 is 1

Step 1: Since 676 > 253, we apply the division lemma to 676 and 253, to get

676 = 253 x 2 + 170

Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 170 and 253, to get

253 = 170 x 1 + 83

Step 3: We consider the new divisor 170 and the new remainder 83, and apply the division lemma to get

170 = 83 x 2 + 4

We consider the new divisor 83 and the new remainder 4,and apply the division lemma to get

83 = 4 x 20 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 253 and 676 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(83,4) = HCF(170,83) = HCF(253,170) = HCF(676,253) .

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

Step 1: Since 33 > 1, we apply the division lemma to 33 and 1, to get

33 = 1 x 33 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 33 is 1

Notice that 1 = HCF(33,1) .
