HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 475, 385 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 475, 385 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 475, 385 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 475, 385 is 5.

HCF(475, 385) = 5

HCF of 475, 385 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 475, 385 is 5.

Highest Common Factor of 475,385 using Euclid's algorithm

Highest Common Factor of 475,385 is 5

Step 1: Since 475 > 385, we apply the division lemma to 475 and 385, to get

475 = 385 x 1 + 90

Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 90 and 385, to get

385 = 90 x 4 + 25

Step 3: We consider the new divisor 90 and the new remainder 25, and apply the division lemma to get

90 = 25 x 3 + 15

We consider the new divisor 25 and the new remainder 15,and apply the division lemma to get

25 = 15 x 1 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 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 475 and 385 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(90,25) = HCF(385,90) = HCF(475,385) .
