HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 463, 197, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 463, 197, 949 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 463, 197, 949 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 463, 197, 949 is 1.

HCF(463, 197, 949) = 1

Highest common factor (HCF) of 463, 197, 949 is 1.

Highest Common Factor of 463,197,949 using Euclid's algorithm

Highest Common Factor of 463,197,949 is 1

Step 1: Since 463 > 197, we apply the division lemma to 463 and 197, to get

463 = 197 x 2 + 69

Step 2: Since the reminder 197 ≠ 0, we apply division lemma to 69 and 197, to get

197 = 69 x 2 + 59

Step 3: We consider the new divisor 69 and the new remainder 59, and apply the division lemma to get

69 = 59 x 1 + 10

We consider the new divisor 59 and the new remainder 10,and apply the division lemma to get

59 = 10 x 5 + 9

We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get

10 = 9 x 1 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 463 and 197 is 1

Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(59,10) = HCF(69,59) = HCF(197,69) = HCF(463,197) .

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

Step 1: Since 949 > 1, we apply the division lemma to 949 and 1, to get

949 = 1 x 949 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 949 is 1

Notice that 1 = HCF(949,1) .
