HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 508, 3417, 1455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 508, 3417, 1455 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 508, 3417, 1455 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 508, 3417, 1455 is 1.
HCF(508, 3417, 1455) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 508, 3417, 1455 is 1.
Step 1: Since 3417 > 508, we apply the division lemma to 3417 and 508, to get
3417 = 508 x 6 + 369
Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 369 and 508, to get
508 = 369 x 1 + 139
Step 3: We consider the new divisor 369 and the new remainder 139, and apply the division lemma to get
369 = 139 x 2 + 91
We consider the new divisor 139 and the new remainder 91,and apply the division lemma to get
139 = 91 x 1 + 48
We consider the new divisor 91 and the new remainder 48,and apply the division lemma to get
91 = 48 x 1 + 43
We consider the new divisor 48 and the new remainder 43,and apply the division lemma to get
48 = 43 x 1 + 5
We consider the new divisor 43 and the new remainder 5,and apply the division lemma to get
43 = 5 x 8 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 508 and 3417 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(43,5) = HCF(48,43) = HCF(91,48) = HCF(139,91) = HCF(369,139) = HCF(508,369) = HCF(3417,508) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1455 > 1, we apply the division lemma to 1455 and 1, to get
1455 = 1 x 1455 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1455 is 1
Notice that 1 = HCF(1455,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
