HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 573, 417, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 573, 417, 451 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 573, 417, 451 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 573, 417, 451 is 1.
HCF(573, 417, 451) = 1
HCF of 573, 417, 451 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 573, 417, 451 is 1.
Highest Common Factor of 573,417,451 is 1
Step 1: Since 573 > 417, we apply the division lemma to 573 and 417, to get
573 = 417 x 1 + 156
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 156 and 417, to get
417 = 156 x 2 + 105
Step 3: We consider the new divisor 156 and the new remainder 105, and apply the division lemma to get
156 = 105 x 1 + 51
We consider the new divisor 105 and the new remainder 51,and apply the division lemma to get
105 = 51 x 2 + 3
We consider the new divisor 51 and the new remainder 3,and apply the division lemma to get
51 = 3 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 573 and 417 is 3
Notice that 3 = HCF(51,3) = HCF(105,51) = HCF(156,105) = HCF(417,156) = HCF(573,417) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 451 > 3, we apply the division lemma to 451 and 3, to get
451 = 3 x 150 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 451 is 1
Notice that 1 = HCF(3,1) = HCF(451,3) .
