HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 884, 874 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 884, 874 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 515, 884, 874 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 515, 884, 874 is 1.
HCF(515, 884, 874) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 884, 874 is 1.
Step 1: Since 884 > 515, we apply the division lemma to 884 and 515, to get
884 = 515 x 1 + 369
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 369 and 515, to get
515 = 369 x 1 + 146
Step 3: We consider the new divisor 369 and the new remainder 146, and apply the division lemma to get
369 = 146 x 2 + 77
We consider the new divisor 146 and the new remainder 77,and apply the division lemma to get
146 = 77 x 1 + 69
We consider the new divisor 77 and the new remainder 69,and apply the division lemma to get
77 = 69 x 1 + 8
We consider the new divisor 69 and the new remainder 8,and apply the division lemma to get
69 = 8 x 8 + 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 515 and 884 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(69,8) = HCF(77,69) = HCF(146,77) = HCF(369,146) = HCF(515,369) = HCF(884,515) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 874 > 1, we apply the division lemma to 874 and 1, to get
874 = 1 x 874 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 874 is 1
Notice that 1 = HCF(874,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
