HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 43, 633, 821 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 30, 43, 633, 821 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 30, 43, 633, 821 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 30, 43, 633, 821 is 1.

HCF(30, 43, 633, 821) = 1

HCF of 30, 43, 633, 821 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 30, 43, 633, 821 is 1.

Highest Common Factor of 30,43,633,821 using Euclid's algorithm

Highest Common Factor of 30,43,633,821 is 1

Step 1: Since 43 > 30, we apply the division lemma to 43 and 30, to get

43 = 30 x 1 + 13

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 13 and 30, to get

30 = 13 x 2 + 4

Step 3: We consider the new divisor 13 and the new remainder 4, and apply the division lemma to get

13 = 4 x 3 + 1

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 30 and 43 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(43,30) .

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

Step 1: Since 633 > 1, we apply the division lemma to 633 and 1, to get

633 = 1 x 633 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 633 is 1

Notice that 1 = HCF(633,1) .

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

Step 1: Since 821 > 1, we apply the division lemma to 821 and 1, to get

821 = 1 x 821 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 821 is 1

Notice that 1 = HCF(821,1) .
