HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 353, 544, 620 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 353, 544, 620 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 353, 544, 620 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 353, 544, 620 is 1.

HCF(353, 544, 620) = 1

HCF of 353, 544, 620 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 353, 544, 620 is 1.

Highest Common Factor of 353,544,620 using Euclid's algorithm

Highest Common Factor of 353,544,620 is 1

Step 1: Since 544 > 353, we apply the division lemma to 544 and 353, to get

544 = 353 x 1 + 191

Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 191 and 353, to get

353 = 191 x 1 + 162

Step 3: We consider the new divisor 191 and the new remainder 162, and apply the division lemma to get

191 = 162 x 1 + 29

We consider the new divisor 162 and the new remainder 29,and apply the division lemma to get

162 = 29 x 5 + 17

We consider the new divisor 29 and the new remainder 17,and apply the division lemma to get

29 = 17 x 1 + 12

We consider the new divisor 17 and the new remainder 12,and apply the division lemma to get

17 = 12 x 1 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 353 and 544 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(29,17) = HCF(162,29) = HCF(191,162) = HCF(353,191) = HCF(544,353) .

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

Step 1: Since 620 > 1, we apply the division lemma to 620 and 1, to get

620 = 1 x 620 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 620 is 1

Notice that 1 = HCF(620,1) .
