HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 98811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 98811 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 820, 98811 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 820, 98811 is 1.
HCF(820, 98811) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 98811 is 1.
Step 1: Since 98811 > 820, we apply the division lemma to 98811 and 820, to get
98811 = 820 x 120 + 411
Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 411 and 820, to get
820 = 411 x 1 + 409
Step 3: We consider the new divisor 411 and the new remainder 409, and apply the division lemma to get
411 = 409 x 1 + 2
We consider the new divisor 409 and the new remainder 2,and apply the division lemma to get
409 = 2 x 204 + 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 820 and 98811 is 1
Notice that 1 = HCF(2,1) = HCF(409,2) = HCF(411,409) = HCF(820,411) = HCF(98811,820) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
