HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 100, 330, 915 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 100, 330, 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 100, 330, 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 100, 330, 915 is 5.

HCF(100, 330, 915) = 5

HCF of 100, 330, 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 100, 330, 915 is 5.

Highest Common Factor of 100,330,915 using Euclid's algorithm

Highest Common Factor of 100,330,915 is 5

Step 1: Since 330 > 100, we apply the division lemma to 330 and 100, to get

330 = 100 x 3 + 30

Step 2: Since the reminder 100 ≠ 0, we apply division lemma to 30 and 100, to get

100 = 30 x 3 + 10

Step 3: We consider the new divisor 30 and the new remainder 10, and apply the division lemma to get

30 = 10 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 100 and 330 is 10

Notice that 10 = HCF(30,10) = HCF(100,30) = HCF(330,100) .


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

Step 1: Since 915 > 10, we apply the division lemma to 915 and 10, to get

915 = 10 x 91 + 5

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 5 and 10, 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 10 and 915 is 5

Notice that 5 = HCF(10,5) = HCF(915,10) .
