HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 506, 7497, 4021 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 506, 7497, 4021 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 506, 7497, 4021 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 506, 7497, 4021 is 1.
HCF(506, 7497, 4021) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 506, 7497, 4021 is 1.
Step 1: Since 7497 > 506, we apply the division lemma to 7497 and 506, to get
7497 = 506 x 14 + 413
Step 2: Since the reminder 506 ≠ 0, we apply division lemma to 413 and 506, to get
506 = 413 x 1 + 93
Step 3: We consider the new divisor 413 and the new remainder 93, and apply the division lemma to get
413 = 93 x 4 + 41
We consider the new divisor 93 and the new remainder 41,and apply the division lemma to get
93 = 41 x 2 + 11
We consider the new divisor 41 and the new remainder 11,and apply the division lemma to get
41 = 11 x 3 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 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 506 and 7497 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(41,11) = HCF(93,41) = HCF(413,93) = HCF(506,413) = HCF(7497,506) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4021 > 1, we apply the division lemma to 4021 and 1, to get
4021 = 1 x 4021 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4021 is 1
Notice that 1 = HCF(4021,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
