HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 814, 130, 567 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 814, 130, 567 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 998, 814, 130, 567 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 998, 814, 130, 567 is 1.
HCF(998, 814, 130, 567) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 998, 814, 130, 567 is 1.
Step 1: Since 998 > 814, we apply the division lemma to 998 and 814, to get
998 = 814 x 1 + 184
Step 2: Since the reminder 814 ≠ 0, we apply division lemma to 184 and 814, to get
814 = 184 x 4 + 78
Step 3: We consider the new divisor 184 and the new remainder 78, and apply the division lemma to get
184 = 78 x 2 + 28
We consider the new divisor 78 and the new remainder 28,and apply the division lemma to get
78 = 28 x 2 + 22
We consider the new divisor 28 and the new remainder 22,and apply the division lemma to get
28 = 22 x 1 + 6
We consider the new divisor 22 and the new remainder 6,and apply the division lemma to get
22 = 6 x 3 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 998 and 814 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(28,22) = HCF(78,28) = HCF(184,78) = HCF(814,184) = HCF(998,814) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 130 > 2, we apply the division lemma to 130 and 2, to get
130 = 2 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 130 is 2
Notice that 2 = HCF(130,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 567 > 2, we apply the division lemma to 567 and 2, to get
567 = 2 x 283 + 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 567 is 1
Notice that 1 = HCF(2,1) = HCF(567,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
