HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 8915, 4020 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 909, 8915, 4020 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 909, 8915, 4020 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 909, 8915, 4020 is 1.

HCF(909, 8915, 4020) = 1

Highest common factor (HCF) of 909, 8915, 4020 is 1.

Highest Common Factor of 909,8915,4020 using Euclid's algorithm

Highest Common Factor of 909,8915,4020 is 1

Step 1: Since 8915 > 909, we apply the division lemma to 8915 and 909, to get

8915 = 909 x 9 + 734

Step 2: Since the reminder 909 ≠ 0, we apply division lemma to 734 and 909, to get

909 = 734 x 1 + 175

Step 3: We consider the new divisor 734 and the new remainder 175, and apply the division lemma to get

734 = 175 x 4 + 34

We consider the new divisor 175 and the new remainder 34,and apply the division lemma to get

175 = 34 x 5 + 5

We consider the new divisor 34 and the new remainder 5,and apply the division lemma to get

34 = 5 x 6 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 909 and 8915 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(34,5) = HCF(175,34) = HCF(734,175) = HCF(909,734) = HCF(8915,909) .

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

Step 1: Since 4020 > 1, we apply the division lemma to 4020 and 1, to get

4020 = 1 x 4020 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4020 is 1

Notice that 1 = HCF(4020,1) .
