HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 481, 22 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 694, 481, 22 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 694, 481, 22 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 694, 481, 22 is 1.
HCF(694, 481, 22) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 694, 481, 22 is 1.
Step 1: Since 694 > 481, we apply the division lemma to 694 and 481, to get
694 = 481 x 1 + 213
Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 213 and 481, to get
481 = 213 x 2 + 55
Step 3: We consider the new divisor 213 and the new remainder 55, and apply the division lemma to get
213 = 55 x 3 + 48
We consider the new divisor 55 and the new remainder 48,and apply the division lemma to get
55 = 48 x 1 + 7
We consider the new divisor 48 and the new remainder 7,and apply the division lemma to get
48 = 7 x 6 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 694 and 481 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(48,7) = HCF(55,48) = HCF(213,55) = HCF(481,213) = HCF(694,481) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1
Notice that 1 = HCF(22,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
