HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 748, 193, 413 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 491, 748, 193, 413 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 491, 748, 193, 413 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 491, 748, 193, 413 is 1.

HCF(491, 748, 193, 413) = 1

Highest Common Factor of 491,748,193,413 using Euclid's algorithm

Highest Common Factor of 491,748,193,413 is 1

Step 1: Since 748 > 491, we apply the division lemma to 748 and 491, to get

748 = 491 x 1 + 257

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 257 and 491, to get

491 = 257 x 1 + 234

Step 3: We consider the new divisor 257 and the new remainder 234, and apply the division lemma to get

257 = 234 x 1 + 23

We consider the new divisor 234 and the new remainder 23,and apply the division lemma to get

234 = 23 x 10 + 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 491 and 748 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(234,23) = HCF(257,234) = HCF(491,257) = HCF(748,491) .

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

Step 1: Since 193 > 1, we apply the division lemma to 193 and 1, to get

193 = 1 x 193 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 193 is 1

Notice that 1 = HCF(193,1) .

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

Step 1: Since 413 > 1, we apply the division lemma to 413 and 1, to get

413 = 1 x 413 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 413 is 1

Notice that 1 = HCF(413,1) .
