HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 451, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 451, 71 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 440, 451, 71 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 440, 451, 71 is 1.
HCF(440, 451, 71) = 1
HCF of 440, 451, 71 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 440, 451, 71 is 1.
Highest Common Factor of 440,451,71 is 1
Step 1: Since 451 > 440, we apply the division lemma to 451 and 440, to get
451 = 440 x 1 + 11
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 11 and 440, to get
440 = 11 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 440 and 451 is 11
Notice that 11 = HCF(440,11) = HCF(451,440) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 71 > 11, we apply the division lemma to 71 and 11, to get
71 = 11 x 6 + 5
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 5 and 11, to get
11 = 5 x 2 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 71 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(71,11) .
