HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 100, 456, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 100, 456, 447 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 100, 456, 447 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, 456, 447 is 1.

HCF(100, 456, 447) = 1

Highest common factor (HCF) of 100, 456, 447 is 1.

Highest Common Factor of 100,456,447 using Euclid's algorithm

Highest Common Factor of 100,456,447 is 1

Step 1: Since 456 > 100, we apply the division lemma to 456 and 100, to get

456 = 100 x 4 + 56

Step 2: Since the reminder 100 ≠ 0, we apply division lemma to 56 and 100, to get

100 = 56 x 1 + 44

Step 3: We consider the new divisor 56 and the new remainder 44, and apply the division lemma to get

56 = 44 x 1 + 12

We consider the new divisor 44 and the new remainder 12,and apply the division lemma to get

44 = 12 x 3 + 8

We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get

12 = 8 x 1 + 4

We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 100 and 456 is 4

Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(44,12) = HCF(56,44) = HCF(100,56) = HCF(456,100) .


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

Step 1: Since 447 > 4, we apply the division lemma to 447 and 4, to get

447 = 4 x 111 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 447 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(447,4) .
