HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 432 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 432 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, 432 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, 432 is 1.
HCF(515, 432) = 1
HCF of 515, 432 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 432 is 1.
Highest Common Factor of 515,432 is 1
Step 1: Since 515 > 432, we apply the division lemma to 515 and 432, to get
515 = 432 x 1 + 83
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 83 and 432, to get
432 = 83 x 5 + 17
Step 3: We consider the new divisor 83 and the new remainder 17, and apply the division lemma to get
83 = 17 x 4 + 15
We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get
17 = 15 x 1 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 432 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(83,17) = HCF(432,83) = HCF(515,432) .
