HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 204, 578, 89, 313 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 204, 578, 89, 313 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 204, 578, 89, 313 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 204, 578, 89, 313 is 1.
HCF(204, 578, 89, 313) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 204, 578, 89, 313 is 1.
Step 1: Since 578 > 204, we apply the division lemma to 578 and 204, to get
578 = 204 x 2 + 170
Step 2: Since the reminder 204 ≠ 0, we apply division lemma to 170 and 204, to get
204 = 170 x 1 + 34
Step 3: We consider the new divisor 170 and the new remainder 34, and apply the division lemma to get
170 = 34 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 204 and 578 is 34
Notice that 34 = HCF(170,34) = HCF(204,170) = HCF(578,204) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 89 > 34, we apply the division lemma to 89 and 34, to get
89 = 34 x 2 + 21
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 21 and 34, to get
34 = 21 x 1 + 13
Step 3: We consider the new divisor 21 and the new remainder 13, and apply the division lemma to get
21 = 13 x 1 + 8
We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get
13 = 8 x 1 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 34 and 89 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(89,34) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 313 > 1, we apply the division lemma to 313 and 1, to get
313 = 1 x 313 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 313 is 1
Notice that 1 = HCF(313,1) .
