HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 785, 347 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 785, 347 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 458, 785, 347 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 458, 785, 347 is 1.
HCF(458, 785, 347) = 1
HCF of 458, 785, 347 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 458, 785, 347 is 1.
Highest Common Factor of 458,785,347 is 1
Step 1: Since 785 > 458, we apply the division lemma to 785 and 458, to get
785 = 458 x 1 + 327
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 327 and 458, to get
458 = 327 x 1 + 131
Step 3: We consider the new divisor 327 and the new remainder 131, and apply the division lemma to get
327 = 131 x 2 + 65
We consider the new divisor 131 and the new remainder 65,and apply the division lemma to get
131 = 65 x 2 + 1
We consider the new divisor 65 and the new remainder 1,and apply the division lemma to get
65 = 1 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 458 and 785 is 1
Notice that 1 = HCF(65,1) = HCF(131,65) = HCF(327,131) = HCF(458,327) = HCF(785,458) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 347 > 1, we apply the division lemma to 347 and 1, to get
347 = 1 x 347 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 347 is 1
Notice that 1 = HCF(347,1) .
