HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 807, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 807, 91 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, 807, 91 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, 807, 91 is 1.
HCF(458, 807, 91) = 1
HCF of 458, 807, 91 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, 807, 91 is 1.
Highest Common Factor of 458,807,91 is 1
Step 1: Since 807 > 458, we apply the division lemma to 807 and 458, to get
807 = 458 x 1 + 349
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 349 and 458, to get
458 = 349 x 1 + 109
Step 3: We consider the new divisor 349 and the new remainder 109, and apply the division lemma to get
349 = 109 x 3 + 22
We consider the new divisor 109 and the new remainder 22,and apply the division lemma to get
109 = 22 x 4 + 21
We consider the new divisor 22 and the new remainder 21,and apply the division lemma to get
22 = 21 x 1 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 458 and 807 is 1
Notice that 1 = HCF(21,1) = HCF(22,21) = HCF(109,22) = HCF(349,109) = HCF(458,349) = HCF(807,458) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1
Notice that 1 = HCF(91,1) .
