HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1620, 1951, 31389 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 1620, 1951, 31389 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 1620, 1951, 31389 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 1620, 1951, 31389 is 1.

HCF(1620, 1951, 31389) = 1

HCF of 1620, 1951, 31389 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 1620, 1951, 31389 is 1.

Highest Common Factor of 1620,1951,31389 using Euclid's algorithm

Highest Common Factor of 1620,1951,31389 is 1

Step 1: Since 1951 > 1620, we apply the division lemma to 1951 and 1620, to get

1951 = 1620 x 1 + 331

Step 2: Since the reminder 1620 ≠ 0, we apply division lemma to 331 and 1620, to get

1620 = 331 x 4 + 296

Step 3: We consider the new divisor 331 and the new remainder 296, and apply the division lemma to get

331 = 296 x 1 + 35

We consider the new divisor 296 and the new remainder 35,and apply the division lemma to get

296 = 35 x 8 + 16

We consider the new divisor 35 and the new remainder 16,and apply the division lemma to get

35 = 16 x 2 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

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 1620 and 1951 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(35,16) = HCF(296,35) = HCF(331,296) = HCF(1620,331) = HCF(1951,1620) .

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

Step 1: Since 31389 > 1, we apply the division lemma to 31389 and 1, to get

31389 = 1 x 31389 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 31389 is 1

Notice that 1 = HCF(31389,1) .
