HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 197, 620, 446 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 197, 620, 446 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 197, 620, 446 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 197, 620, 446 is 1.

HCF(197, 620, 446) = 1

Highest common factor (HCF) of 197, 620, 446 is 1.

Highest Common Factor of 197,620,446 using Euclid's algorithm

Highest Common Factor of 197,620,446 is 1

Step 1: Since 620 > 197, we apply the division lemma to 620 and 197, to get

620 = 197 x 3 + 29

Step 2: Since the reminder 197 ≠ 0, we apply division lemma to 29 and 197, to get

197 = 29 x 6 + 23

Step 3: We consider the new divisor 29 and the new remainder 23, and apply the division lemma to get

29 = 23 x 1 + 6

We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get

23 = 6 x 3 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 197 and 620 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(197,29) = HCF(620,197) .

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

Step 1: Since 446 > 1, we apply the division lemma to 446 and 1, to get

446 = 1 x 446 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 446 is 1

Notice that 1 = HCF(446,1) .
