HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 45, 868 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 45, 868 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 45, 868 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 45, 868 is 1.

HCF(45, 868) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 45, 868 is 1.

Highest Common Factor of 45,868 using Euclid's algorithm

Highest Common Factor of 45,868 is 1

Step 1: Since 868 > 45, we apply the division lemma to 868 and 45, to get

868 = 45 x 19 + 13

Step 2: Since the reminder 45 ≠ 0, we apply division lemma to 13 and 45, to get

45 = 13 x 3 + 6

Step 3: We consider the new divisor 13 and the new remainder 6, and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 45 and 868 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(45,13) = HCF(868,45) .
