HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 561, 882 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 398, 561, 882 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 398, 561, 882 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 398, 561, 882 is 1.
HCF(398, 561, 882) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 398, 561, 882 is 1.
Step 1: Since 561 > 398, we apply the division lemma to 561 and 398, to get
561 = 398 x 1 + 163
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 163 and 398, to get
398 = 163 x 2 + 72
Step 3: We consider the new divisor 163 and the new remainder 72, and apply the division lemma to get
163 = 72 x 2 + 19
We consider the new divisor 72 and the new remainder 19,and apply the division lemma to get
72 = 19 x 3 + 15
We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get
19 = 15 x 1 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 398 and 561 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(72,19) = HCF(163,72) = HCF(398,163) = HCF(561,398) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 882 > 1, we apply the division lemma to 882 and 1, to get
882 = 1 x 882 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 882 is 1
Notice that 1 = HCF(882,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
