HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 513, 805, 81, 948 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 513, 805, 81, 948 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 513, 805, 81, 948 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 513, 805, 81, 948 is 1.
HCF(513, 805, 81, 948) = 1
HCF of 513, 805, 81, 948 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 513, 805, 81, 948 is 1.
Highest Common Factor of 513,805,81,948 is 1
Step 1: Since 805 > 513, we apply the division lemma to 805 and 513, to get
805 = 513 x 1 + 292
Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 292 and 513, to get
513 = 292 x 1 + 221
Step 3: We consider the new divisor 292 and the new remainder 221, and apply the division lemma to get
292 = 221 x 1 + 71
We consider the new divisor 221 and the new remainder 71,and apply the division lemma to get
221 = 71 x 3 + 8
We consider the new divisor 71 and the new remainder 8,and apply the division lemma to get
71 = 8 x 8 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 513 and 805 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(71,8) = HCF(221,71) = HCF(292,221) = HCF(513,292) = HCF(805,513) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 81 > 1, we apply the division lemma to 81 and 1, to get
81 = 1 x 81 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 81 is 1
Notice that 1 = HCF(81,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 948 > 1, we apply the division lemma to 948 and 1, to get
948 = 1 x 948 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 948 is 1
Notice that 1 = HCF(948,1) .
