HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9915, 4115, 99234 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 9915, 4115, 99234 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 9915, 4115, 99234 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 9915, 4115, 99234 is 1.

HCF(9915, 4115, 99234) = 1

Highest common factor (HCF) of 9915, 4115, 99234 is 1.

Highest Common Factor of 9915,4115,99234 using Euclid's algorithm

Highest Common Factor of 9915,4115,99234 is 1

Step 1: Since 9915 > 4115, we apply the division lemma to 9915 and 4115, to get

9915 = 4115 x 2 + 1685

Step 2: Since the reminder 4115 ≠ 0, we apply division lemma to 1685 and 4115, to get

4115 = 1685 x 2 + 745

Step 3: We consider the new divisor 1685 and the new remainder 745, and apply the division lemma to get

1685 = 745 x 2 + 195

We consider the new divisor 745 and the new remainder 195,and apply the division lemma to get

745 = 195 x 3 + 160

We consider the new divisor 195 and the new remainder 160,and apply the division lemma to get

195 = 160 x 1 + 35

We consider the new divisor 160 and the new remainder 35,and apply the division lemma to get

160 = 35 x 4 + 20

We consider the new divisor 35 and the new remainder 20,and apply the division lemma to get

35 = 20 x 1 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 9915 and 4115 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(35,20) = HCF(160,35) = HCF(195,160) = HCF(745,195) = HCF(1685,745) = HCF(4115,1685) = HCF(9915,4115) .

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

Step 1: Since 99234 > 5, we apply the division lemma to 99234 and 5, to get

99234 = 5 x 19846 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: 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 5 and 99234 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(99234,5) .
