HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 915 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 915 is 5 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 485, 915 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 485, 915 is 5.

HCF(485, 915) = 5

HCF of 485, 915 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 485, 915 is 5.

Highest Common Factor of 485,915 using Euclid's algorithm

Highest Common Factor of 485,915 is 5

Step 1: Since 915 > 485, we apply the division lemma to 915 and 485, to get

915 = 485 x 1 + 430

Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 430 and 485, to get

485 = 430 x 1 + 55

Step 3: We consider the new divisor 430 and the new remainder 55, and apply the division lemma to get

430 = 55 x 7 + 45

We consider the new divisor 55 and the new remainder 45,and apply the division lemma to get

55 = 45 x 1 + 10

We consider the new divisor 45 and the new remainder 10,and apply the division lemma to get

45 = 10 x 4 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 485 and 915 is 5

Notice that 5 = HCF(10,5) = HCF(45,10) = HCF(55,45) = HCF(430,55) = HCF(485,430) = HCF(915,485) .
