HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 850, 223, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 515, 850, 223, 647 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 515, 850, 223, 647 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 515, 850, 223, 647 is 1.

HCF(515, 850, 223, 647) = 1

Highest Common Factor of 515,850,223,647 using Euclid's algorithm

Highest Common Factor of 515,850,223,647 is 1

Step 1: Since 850 > 515, we apply the division lemma to 850 and 515, to get

850 = 515 x 1 + 335

Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 335 and 515, to get

515 = 335 x 1 + 180

Step 3: We consider the new divisor 335 and the new remainder 180, and apply the division lemma to get

335 = 180 x 1 + 155

We consider the new divisor 180 and the new remainder 155,and apply the division lemma to get

180 = 155 x 1 + 25

We consider the new divisor 155 and the new remainder 25,and apply the division lemma to get

155 = 25 x 6 + 5

We consider the new divisor 25 and the new remainder 5,and apply the division lemma to get

25 = 5 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 515 and 850 is 5

Notice that 5 = HCF(25,5) = HCF(155,25) = HCF(180,155) = HCF(335,180) = HCF(515,335) = HCF(850,515) .


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

Step 1: Since 223 > 5, we apply the division lemma to 223 and 5, to get

223 = 5 x 44 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 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 5 and 223 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(223,5) .


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

Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get

647 = 1 x 647 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1

Notice that 1 = HCF(647,1) .
