HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 45, 495, 515 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 45, 495, 515 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 45, 495, 515 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 45, 495, 515 is 5.
HCF(45, 495, 515) = 5
HCF of 45, 495, 515 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 45, 495, 515 is 5.
Highest Common Factor of 45,495,515 is 5
Step 1: Since 495 > 45, we apply the division lemma to 495 and 45, to get
495 = 45 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 45 and 495 is 45
Notice that 45 = HCF(495,45) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 515 > 45, we apply the division lemma to 515 and 45, to get
515 = 45 x 11 + 20
Step 2: Since the reminder 45 ≠ 0, we apply division lemma to 20 and 45, to get
45 = 20 x 2 + 5
Step 3: We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 45 and 515 is 5
Notice that 5 = HCF(20,5) = HCF(45,20) = HCF(515,45) .
