HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 446, 250, 381, 49 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 446, 250, 381, 49 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 446, 250, 381, 49 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 446, 250, 381, 49 is 1.
HCF(446, 250, 381, 49) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 446, 250, 381, 49 is 1.
Step 1: Since 446 > 250, we apply the division lemma to 446 and 250, to get
446 = 250 x 1 + 196
Step 2: Since the reminder 250 ≠ 0, we apply division lemma to 196 and 250, to get
250 = 196 x 1 + 54
Step 3: We consider the new divisor 196 and the new remainder 54, and apply the division lemma to get
196 = 54 x 3 + 34
We consider the new divisor 54 and the new remainder 34,and apply the division lemma to get
54 = 34 x 1 + 20
We consider the new divisor 34 and the new remainder 20,and apply the division lemma to get
34 = 20 x 1 + 14
We consider the new divisor 20 and the new remainder 14,and apply the division lemma to get
20 = 14 x 1 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 446 and 250 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(34,20) = HCF(54,34) = HCF(196,54) = HCF(250,196) = HCF(446,250) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 381 > 2, we apply the division lemma to 381 and 2, to get
381 = 2 x 190 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 381 is 1
Notice that 1 = HCF(2,1) = HCF(381,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 1, we apply the division lemma to 49 and 1, to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 49 is 1
Notice that 1 = HCF(49,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 446, 250, 381, 49?
Answer: HCF of 446, 250, 381, 49 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 446, 250, 381, 49 using Euclid's Algorithm?
