HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 115 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 115 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 870, 115 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 870, 115 is 5.
HCF(870, 115) = 5
HCF of 870, 115 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 115 is 5.
Highest Common Factor of 870,115 is 5
Step 1: Since 870 > 115, we apply the division lemma to 870 and 115, to get
870 = 115 x 7 + 65
Step 2: Since the reminder 115 ≠ 0, we apply division lemma to 65 and 115, to get
115 = 65 x 1 + 50
Step 3: We consider the new divisor 65 and the new remainder 50, and apply the division lemma to get
65 = 50 x 1 + 15
We consider the new divisor 50 and the new remainder 15,and apply the division lemma to get
50 = 15 x 3 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 870 and 115 is 5
Notice that 5 = HCF(15,5) = HCF(50,15) = HCF(65,50) = HCF(115,65) = HCF(870,115) .
