HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 405, 297, 576, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 405, 297, 576, 31 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 405, 297, 576, 31 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 405, 297, 576, 31 is 1.
HCF(405, 297, 576, 31) = 1
HCF of 405, 297, 576, 31 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 405, 297, 576, 31 is 1.
Highest Common Factor of 405,297,576,31 is 1
Step 1: Since 405 > 297, we apply the division lemma to 405 and 297, to get
405 = 297 x 1 + 108
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 108 and 297, to get
297 = 108 x 2 + 81
Step 3: We consider the new divisor 108 and the new remainder 81, and apply the division lemma to get
108 = 81 x 1 + 27
We consider the new divisor 81 and the new remainder 27, and apply the division lemma to get
81 = 27 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 405 and 297 is 27
Notice that 27 = HCF(81,27) = HCF(108,81) = HCF(297,108) = HCF(405,297) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 576 > 27, we apply the division lemma to 576 and 27, to get
576 = 27 x 21 + 9
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 9 and 27, to get
27 = 9 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 27 and 576 is 9
Notice that 9 = HCF(27,9) = HCF(576,27) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31 > 9, we apply the division lemma to 31 and 9, to get
31 = 9 x 3 + 4
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 4 and 9, to get
9 = 4 x 2 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 31 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) .
