HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 150, 115 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 150, 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 150, 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 150, 115 is 5.
HCF(150, 115) = 5
HCF of 150, 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 150, 115 is 5.
Highest Common Factor of 150,115 is 5
Step 1: Since 150 > 115, we apply the division lemma to 150 and 115, to get
150 = 115 x 1 + 35
Step 2: Since the reminder 115 ≠ 0, we apply division lemma to 35 and 115, to get
115 = 35 x 3 + 10
Step 3: We consider the new divisor 35 and the new remainder 10, and apply the division lemma to get
35 = 10 x 3 + 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 150 and 115 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(115,35) = HCF(150,115) .
