HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 392, 78961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 392, 78961 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 392, 78961 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 392, 78961 is 1.
HCF(392, 78961) = 1
HCF of 392, 78961 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 392, 78961 is 1.
Highest Common Factor of 392,78961 is 1
Step 1: Since 78961 > 392, we apply the division lemma to 78961 and 392, to get
78961 = 392 x 201 + 169
Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 169 and 392, to get
392 = 169 x 2 + 54
Step 3: We consider the new divisor 169 and the new remainder 54, and apply the division lemma to get
169 = 54 x 3 + 7
We consider the new divisor 54 and the new remainder 7,and apply the division lemma to get
54 = 7 x 7 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 392 and 78961 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(54,7) = HCF(169,54) = HCF(392,169) = HCF(78961,392) .
