HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 2290 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 2290 is 5 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 805, 2290 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 805, 2290 is 5.
HCF(805, 2290) = 5
HCF of 805, 2290 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 805, 2290 is 5.
Highest Common Factor of 805,2290 is 5
Step 1: Since 2290 > 805, we apply the division lemma to 2290 and 805, to get
2290 = 805 x 2 + 680
Step 2: Since the reminder 805 ≠ 0, we apply division lemma to 680 and 805, to get
805 = 680 x 1 + 125
Step 3: We consider the new divisor 680 and the new remainder 125, and apply the division lemma to get
680 = 125 x 5 + 55
We consider the new divisor 125 and the new remainder 55,and apply the division lemma to get
125 = 55 x 2 + 15
We consider the new divisor 55 and the new remainder 15,and apply the division lemma to get
55 = 15 x 3 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 805 and 2290 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(55,15) = HCF(125,55) = HCF(680,125) = HCF(805,680) = HCF(2290,805) .
