HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 576, 987, 443 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 576, 987, 443 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 576, 987, 443 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 576, 987, 443 is 1.
HCF(576, 987, 443) = 1
HCF of 576, 987, 443 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 576, 987, 443 is 1.
Highest Common Factor of 576,987,443 is 1
Step 1: Since 987 > 576, we apply the division lemma to 987 and 576, to get
987 = 576 x 1 + 411
Step 2: Since the reminder 576 ≠ 0, we apply division lemma to 411 and 576, to get
576 = 411 x 1 + 165
Step 3: We consider the new divisor 411 and the new remainder 165, and apply the division lemma to get
411 = 165 x 2 + 81
We consider the new divisor 165 and the new remainder 81,and apply the division lemma to get
165 = 81 x 2 + 3
We consider the new divisor 81 and the new remainder 3,and apply the division lemma to get
81 = 3 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 576 and 987 is 3
Notice that 3 = HCF(81,3) = HCF(165,81) = HCF(411,165) = HCF(576,411) = HCF(987,576) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 443 > 3, we apply the division lemma to 443 and 3, to get
443 = 3 x 147 + 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 443 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(443,3) .
