HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 480, 319, 17 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 622, 480, 319, 17 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 622, 480, 319, 17 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 622, 480, 319, 17 is 1.
HCF(622, 480, 319, 17) = 1
HCF of 622, 480, 319, 17 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 622, 480, 319, 17 is 1.
Highest Common Factor of 622,480,319,17 is 1
Step 1: Since 622 > 480, we apply the division lemma to 622 and 480, to get
622 = 480 x 1 + 142
Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 142 and 480, to get
480 = 142 x 3 + 54
Step 3: We consider the new divisor 142 and the new remainder 54, and apply the division lemma to get
142 = 54 x 2 + 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 622 and 480 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(34,20) = HCF(54,34) = HCF(142,54) = HCF(480,142) = HCF(622,480) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 319 > 2, we apply the division lemma to 319 and 2, to get
319 = 2 x 159 + 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 319 is 1
Notice that 1 = HCF(2,1) = HCF(319,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 17 > 1, we apply the division lemma to 17 and 1, to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 17 is 1
Notice that 1 = HCF(17,1) .
