HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 571, 256 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 451, 571, 256 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 451, 571, 256 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 451, 571, 256 is 1.
HCF(451, 571, 256) = 1
HCF of 451, 571, 256 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 451, 571, 256 is 1.
Highest Common Factor of 451,571,256 is 1
Step 1: Since 571 > 451, we apply the division lemma to 571 and 451, to get
571 = 451 x 1 + 120
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 120 and 451, to get
451 = 120 x 3 + 91
Step 3: We consider the new divisor 120 and the new remainder 91, and apply the division lemma to get
120 = 91 x 1 + 29
We consider the new divisor 91 and the new remainder 29,and apply the division lemma to get
91 = 29 x 3 + 4
We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get
29 = 4 x 7 + 1
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 451 and 571 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(91,29) = HCF(120,91) = HCF(451,120) = HCF(571,451) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 256 > 1, we apply the division lemma to 256 and 1, to get
256 = 1 x 256 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 256 is 1
Notice that 1 = HCF(256,1) .
