HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 566, 645, 401 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 566, 645, 401 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 566, 645, 401 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 566, 645, 401 is 1.
HCF(566, 645, 401) = 1
HCF of 566, 645, 401 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 566, 645, 401 is 1.
Highest Common Factor of 566,645,401 is 1
Step 1: Since 645 > 566, we apply the division lemma to 645 and 566, to get
645 = 566 x 1 + 79
Step 2: Since the reminder 566 ≠ 0, we apply division lemma to 79 and 566, to get
566 = 79 x 7 + 13
Step 3: We consider the new divisor 79 and the new remainder 13, and apply the division lemma to get
79 = 13 x 6 + 1
We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 566 and 645 is 1
Notice that 1 = HCF(13,1) = HCF(79,13) = HCF(566,79) = HCF(645,566) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 401 > 1, we apply the division lemma to 401 and 1, to get
401 = 1 x 401 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 401 is 1
Notice that 1 = HCF(401,1) .
