HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 363, 405, 696, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 363, 405, 696, 74 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 363, 405, 696, 74 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 363, 405, 696, 74 is 1.
HCF(363, 405, 696, 74) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 363, 405, 696, 74 is 1.
Step 1: Since 405 > 363, we apply the division lemma to 405 and 363, to get
405 = 363 x 1 + 42
Step 2: Since the reminder 363 ≠ 0, we apply division lemma to 42 and 363, to get
363 = 42 x 8 + 27
Step 3: We consider the new divisor 42 and the new remainder 27, and apply the division lemma to get
42 = 27 x 1 + 15
We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get
27 = 15 x 1 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 363 and 405 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(363,42) = HCF(405,363) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 696 > 3, we apply the division lemma to 696 and 3, to get
696 = 3 x 232 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 696 is 3
Notice that 3 = HCF(696,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 74 > 3, we apply the division lemma to 74 and 3, to get
74 = 3 x 24 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 74 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(74,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
