HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 858 i.e. 13 the largest integer that leaves a remainder zero for all numbers.

HCF of 845, 858 is 13 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 845, 858 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 845, 858 is 13.

HCF(845, 858) = 13

HCF of 845, 858 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 845, 858 is 13.

Highest Common Factor of 845,858 using Euclid's algorithm

Highest Common Factor of 845,858 is 13

Step 1: Since 858 > 845, we apply the division lemma to 858 and 845, to get

858 = 845 x 1 + 13

Step 2: Since the reminder 845 ≠ 0, we apply division lemma to 13 and 845, to get

845 = 13 x 65 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 845 and 858 is 13

Notice that 13 = HCF(845,13) = HCF(858,845) .
