HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 465 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 545, 465 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 545, 465 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 545, 465 is 5.
HCF(545, 465) = 5
HCF of 545, 465 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 545, 465 is 5.
Highest Common Factor of 545,465 is 5
Step 1: Since 545 > 465, we apply the division lemma to 545 and 465, to get
545 = 465 x 1 + 80
Step 2: Since the reminder 465 ≠ 0, we apply division lemma to 80 and 465, to get
465 = 80 x 5 + 65
Step 3: We consider the new divisor 80 and the new remainder 65, and apply the division lemma to get
80 = 65 x 1 + 15
We consider the new divisor 65 and the new remainder 15,and apply the division lemma to get
65 = 15 x 4 + 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 545 and 465 is 5
Notice that 5 = HCF(15,5) = HCF(65,15) = HCF(80,65) = HCF(465,80) = HCF(545,465) .
