HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 446, 378 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 321, 446, 378 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 321, 446, 378 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 321, 446, 378 is 1.
HCF(321, 446, 378) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 321, 446, 378 is 1.
Step 1: Since 446 > 321, we apply the division lemma to 446 and 321, to get
446 = 321 x 1 + 125
Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 125 and 321, to get
321 = 125 x 2 + 71
Step 3: We consider the new divisor 125 and the new remainder 71, and apply the division lemma to get
125 = 71 x 1 + 54
We consider the new divisor 71 and the new remainder 54,and apply the division lemma to get
71 = 54 x 1 + 17
We consider the new divisor 54 and the new remainder 17,and apply the division lemma to get
54 = 17 x 3 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 321 and 446 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(54,17) = HCF(71,54) = HCF(125,71) = HCF(321,125) = HCF(446,321) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 378 > 1, we apply the division lemma to 378 and 1, to get
378 = 1 x 378 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 378 is 1
Notice that 1 = HCF(378,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 321, 446, 378?
Answer: HCF of 321, 446, 378 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 321, 446, 378 using Euclid's Algorithm?
Answer: For arbitrary numbers 321, 446, 378 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
