HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 982, 551, 801 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 982, 551, 801 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 982, 551, 801 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 982, 551, 801 is 1.
HCF(982, 551, 801) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 982, 551, 801 is 1.
Step 1: Since 982 > 551, we apply the division lemma to 982 and 551, to get
982 = 551 x 1 + 431
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 431 and 551, to get
551 = 431 x 1 + 120
Step 3: We consider the new divisor 431 and the new remainder 120, and apply the division lemma to get
431 = 120 x 3 + 71
We consider the new divisor 120 and the new remainder 71,and apply the division lemma to get
120 = 71 x 1 + 49
We consider the new divisor 71 and the new remainder 49,and apply the division lemma to get
71 = 49 x 1 + 22
We consider the new divisor 49 and the new remainder 22,and apply the division lemma to get
49 = 22 x 2 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 982 and 551 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(49,22) = HCF(71,49) = HCF(120,71) = HCF(431,120) = HCF(551,431) = HCF(982,551) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 801 > 1, we apply the division lemma to 801 and 1, to get
801 = 1 x 801 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 801 is 1
Notice that 1 = HCF(801,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
