HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 506, 477 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 506, 477 is 1 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 315, 506, 477 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 315, 506, 477 is 1.
HCF(315, 506, 477) = 1
HCF of 315, 506, 477 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 506, 477 is 1.
Highest Common Factor of 315,506,477 is 1
Step 1: Since 506 > 315, we apply the division lemma to 506 and 315, to get
506 = 315 x 1 + 191
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 191 and 315, to get
315 = 191 x 1 + 124
Step 3: We consider the new divisor 191 and the new remainder 124, and apply the division lemma to get
191 = 124 x 1 + 67
We consider the new divisor 124 and the new remainder 67,and apply the division lemma to get
124 = 67 x 1 + 57
We consider the new divisor 67 and the new remainder 57,and apply the division lemma to get
67 = 57 x 1 + 10
We consider the new divisor 57 and the new remainder 10,and apply the division lemma to get
57 = 10 x 5 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 315 and 506 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(57,10) = HCF(67,57) = HCF(124,67) = HCF(191,124) = HCF(315,191) = HCF(506,315) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 477 > 1, we apply the division lemma to 477 and 1, to get
477 = 1 x 477 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 477 is 1
Notice that 1 = HCF(477,1) .
