HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4495, 1821 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 4495, 1821 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 4495, 1821 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 4495, 1821 is 1.
HCF(4495, 1821) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4495, 1821 is 1.
Step 1: Since 4495 > 1821, we apply the division lemma to 4495 and 1821, to get
4495 = 1821 x 2 + 853
Step 2: Since the reminder 1821 ≠ 0, we apply division lemma to 853 and 1821, to get
1821 = 853 x 2 + 115
Step 3: We consider the new divisor 853 and the new remainder 115, and apply the division lemma to get
853 = 115 x 7 + 48
We consider the new divisor 115 and the new remainder 48,and apply the division lemma to get
115 = 48 x 2 + 19
We consider the new divisor 48 and the new remainder 19,and apply the division lemma to get
48 = 19 x 2 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4495 and 1821 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(48,19) = HCF(115,48) = HCF(853,115) = HCF(1821,853) = HCF(4495,1821) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
