HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8365, 4205, 99534 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8365, 4205, 99534 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 8365, 4205, 99534 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 8365, 4205, 99534 is 1.
HCF(8365, 4205, 99534) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8365, 4205, 99534 is 1.
Step 1: Since 8365 > 4205, we apply the division lemma to 8365 and 4205, to get
8365 = 4205 x 1 + 4160
Step 2: Since the reminder 4205 ≠ 0, we apply division lemma to 4160 and 4205, to get
4205 = 4160 x 1 + 45
Step 3: We consider the new divisor 4160 and the new remainder 45, and apply the division lemma to get
4160 = 45 x 92 + 20
We consider the new divisor 45 and the new remainder 20,and apply the division lemma to get
45 = 20 x 2 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 8365 and 4205 is 5
Notice that 5 = HCF(20,5) = HCF(45,20) = HCF(4160,45) = HCF(4205,4160) = HCF(8365,4205) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 99534 > 5, we apply the division lemma to 99534 and 5, to get
99534 = 5 x 19906 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: 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 5 and 99534 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(99534,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
