HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 78 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 78 is 2 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 434, 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 434, 78 is 2.
HCF(434, 78) = 2
HCF of 434, 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 434, 78 is 2.
Highest Common Factor of 434,78 is 2
Step 1: Since 434 > 78, we apply the division lemma to 434 and 78, to get
434 = 78 x 5 + 44
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 44 and 78, to get
78 = 44 x 1 + 34
Step 3: We consider the new divisor 44 and the new remainder 34, and apply the division lemma to get
44 = 34 x 1 + 10
We consider the new divisor 34 and the new remainder 10,and apply the division lemma to get
34 = 10 x 3 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 434 and 78 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(34,10) = HCF(44,34) = HCF(78,44) = HCF(434,78) .
