HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 363, 159, 665 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 363, 159, 665 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, 159, 665 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, 159, 665 is 1.
HCF(363, 159, 665) = 1
HCF of 363, 159, 665 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 363, 159, 665 is 1.
Highest Common Factor of 363,159,665 is 1
Step 1: Since 363 > 159, we apply the division lemma to 363 and 159, to get
363 = 159 x 2 + 45
Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 45 and 159, to get
159 = 45 x 3 + 24
Step 3: We consider the new divisor 45 and the new remainder 24, and apply the division lemma to get
45 = 24 x 1 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 363 and 159 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(45,24) = HCF(159,45) = HCF(363,159) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 665 > 3, we apply the division lemma to 665 and 3, to get
665 = 3 x 221 + 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 665 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(665,3) .
