HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 448, 356, 800, 21 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 448, 356, 800, 21 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 448, 356, 800, 21 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 448, 356, 800, 21 is 1.

HCF(448, 356, 800, 21) = 1

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

HCF of:

Highest common factor (HCF) of 448, 356, 800, 21 is 1.

Highest Common Factor of 448,356,800,21 using Euclid's algorithm

Highest Common Factor of 448,356,800,21 is 1

Step 1: Since 448 > 356, we apply the division lemma to 448 and 356, to get

448 = 356 x 1 + 92

Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 92 and 356, to get

356 = 92 x 3 + 80

Step 3: We consider the new divisor 92 and the new remainder 80, and apply the division lemma to get

92 = 80 x 1 + 12

We consider the new divisor 80 and the new remainder 12,and apply the division lemma to get

80 = 12 x 6 + 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 448 and 356 is 4

Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(80,12) = HCF(92,80) = HCF(356,92) = HCF(448,356) .


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

Step 1: Since 800 > 4, we apply the division lemma to 800 and 4, to get

800 = 4 x 200 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 800 is 4

Notice that 4 = HCF(800,4) .


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

Step 1: Since 21 > 4, we apply the division lemma to 21 and 4, to get

21 = 4 x 5 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 21 is 1

Notice that 1 = HCF(4,1) = HCF(21,4) .
