HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 463, 787 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 463, 787 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 463, 787 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 463, 787 is 1.
HCF(463, 787) = 1
HCF of 463, 787 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 463, 787 is 1.
Highest Common Factor of 463,787 is 1
Step 1: Since 787 > 463, we apply the division lemma to 787 and 463, to get
787 = 463 x 1 + 324
Step 2: Since the reminder 463 ≠ 0, we apply division lemma to 324 and 463, to get
463 = 324 x 1 + 139
Step 3: We consider the new divisor 324 and the new remainder 139, and apply the division lemma to get
324 = 139 x 2 + 46
We consider the new divisor 139 and the new remainder 46,and apply the division lemma to get
139 = 46 x 3 + 1
We consider the new divisor 46 and the new remainder 1,and apply the division lemma to get
46 = 1 x 46 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 463 and 787 is 1
Notice that 1 = HCF(46,1) = HCF(139,46) = HCF(324,139) = HCF(463,324) = HCF(787,463) .
