HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 607, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 607, 78 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 607, 78 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 607, 78 is 1.
HCF(607, 78) = 1
HCF of 607, 78 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 607, 78 is 1.
Highest Common Factor of 607,78 is 1
Step 1: Since 607 > 78, we apply the division lemma to 607 and 78, to get
607 = 78 x 7 + 61
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 61 and 78, to get
78 = 61 x 1 + 17
Step 3: We consider the new divisor 61 and the new remainder 17, and apply the division lemma to get
61 = 17 x 3 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 607 and 78 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(61,17) = HCF(78,61) = HCF(607,78) .
