HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 815, 292, 178, 130 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 815, 292, 178, 130 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 815, 292, 178, 130 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 815, 292, 178, 130 is 1.
HCF(815, 292, 178, 130) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 815, 292, 178, 130 is 1.
Step 1: Since 815 > 292, we apply the division lemma to 815 and 292, to get
815 = 292 x 2 + 231
Step 2: Since the reminder 292 ≠ 0, we apply division lemma to 231 and 292, to get
292 = 231 x 1 + 61
Step 3: We consider the new divisor 231 and the new remainder 61, and apply the division lemma to get
231 = 61 x 3 + 48
We consider the new divisor 61 and the new remainder 48,and apply the division lemma to get
61 = 48 x 1 + 13
We consider the new divisor 48 and the new remainder 13,and apply the division lemma to get
48 = 13 x 3 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 815 and 292 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(48,13) = HCF(61,48) = HCF(231,61) = HCF(292,231) = HCF(815,292) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 178 > 1, we apply the division lemma to 178 and 1, to get
178 = 1 x 178 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 178 is 1
Notice that 1 = HCF(178,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 130 > 1, we apply the division lemma to 130 and 1, to get
130 = 1 x 130 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 130 is 1
Notice that 1 = HCF(130,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
