HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 16, 36, 80, 100 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 16, 36, 80, 100 is 4 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 16, 36, 80, 100 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 16, 36, 80, 100 is **4**.

HCF(16, 36, 80, 100) = 4

*Highest common factor* or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 16, 36, 80, 100 is **4**.

**Step 1:** Since 36 > 16, we apply the division lemma to 36 and 16, to get

36 = 16 x 2 + 4

**Step 2:** Since the reminder 16 ≠ 0, we apply division lemma to 4 and 16, to get

16 = 4 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 16 and 36 is 4

Notice that 4 = HCF(16,4) = HCF(36,16) .

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

**Step 1:** Since 80 > 4, we apply the division lemma to 80 and 4, to get

80 = 4 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 80 is 4

Notice that 4 = HCF(80,4) .

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

**Step 1:** Since 100 > 4, we apply the division lemma to 100 and 4, to get

100 = 4 x 25 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 100 is 4

Notice that 4 = HCF(100,4) .

2. what is the HCF of 16, 36, 80, 100?

Answer: HCF of 16, 36, 80, 100 is 4 the largest number that divides all the numbers leaving a remainder zero.

3. How to find HCF of 16, 36, 80, 100 using Euclid's Algorithm?

Answer: For arbitrary numbers 16, 36, 80, 100 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
