HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 845 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 845 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 240, 845 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 240, 845 is 5.
HCF(240, 845) = 5
HCF of 240, 845 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 845 is 5.
Highest Common Factor of 240,845 is 5
Step 1: Since 845 > 240, we apply the division lemma to 845 and 240, to get
845 = 240 x 3 + 125
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 125 and 240, to get
240 = 125 x 1 + 115
Step 3: We consider the new divisor 125 and the new remainder 115, and apply the division lemma to get
125 = 115 x 1 + 10
We consider the new divisor 115 and the new remainder 10,and apply the division lemma to get
115 = 10 x 11 + 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 240 and 845 is 5
Notice that 5 = HCF(10,5) = HCF(115,10) = HCF(125,115) = HCF(240,125) = HCF(845,240) .
