HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 196, 953 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 515, 196, 953 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, 196, 953 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, 196, 953 is 1.

HCF(515, 196, 953) = 1

Highest common factor (HCF) of 515, 196, 953 is 1.

Highest Common Factor of 515,196,953 using Euclid's algorithm

Highest Common Factor of 515,196,953 is 1

Step 1: Since 515 > 196, we apply the division lemma to 515 and 196, to get

515 = 196 x 2 + 123

Step 2: Since the reminder 196 ≠ 0, we apply division lemma to 123 and 196, to get

196 = 123 x 1 + 73

Step 3: We consider the new divisor 123 and the new remainder 73, and apply the division lemma to get

123 = 73 x 1 + 50

We consider the new divisor 73 and the new remainder 50,and apply the division lemma to get

73 = 50 x 1 + 23

We consider the new divisor 50 and the new remainder 23,and apply the division lemma to get

50 = 23 x 2 + 4

We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get

23 = 4 x 5 + 3

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

4 = 3 x 1 + 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 515 and 196 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(50,23) = HCF(73,50) = HCF(123,73) = HCF(196,123) = HCF(515,196) .

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

Step 1: Since 953 > 1, we apply the division lemma to 953 and 1, to get

953 = 1 x 953 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 953 is 1

Notice that 1 = HCF(953,1) .
