HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 4958 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 4958 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 787, 4958 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 787, 4958 is 1.
HCF(787, 4958) = 1
HCF of 787, 4958 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 787, 4958 is 1.
Highest Common Factor of 787,4958 is 1
Step 1: Since 4958 > 787, we apply the division lemma to 4958 and 787, to get
4958 = 787 x 6 + 236
Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 236 and 787, to get
787 = 236 x 3 + 79
Step 3: We consider the new divisor 236 and the new remainder 79, and apply the division lemma to get
236 = 79 x 2 + 78
We consider the new divisor 79 and the new remainder 78,and apply the division lemma to get
79 = 78 x 1 + 1
We consider the new divisor 78 and the new remainder 1,and apply the division lemma to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 4958 is 1
Notice that 1 = HCF(78,1) = HCF(79,78) = HCF(236,79) = HCF(787,236) = HCF(4958,787) .
