HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 67145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 67145 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 434, 67145 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, 67145 is 1.
HCF(434, 67145) = 1
HCF of 434, 67145 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, 67145 is 1.
Highest Common Factor of 434,67145 is 1
Step 1: Since 67145 > 434, we apply the division lemma to 67145 and 434, to get
67145 = 434 x 154 + 309
Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 309 and 434, to get
434 = 309 x 1 + 125
Step 3: We consider the new divisor 309 and the new remainder 125, and apply the division lemma to get
309 = 125 x 2 + 59
We consider the new divisor 125 and the new remainder 59,and apply the division lemma to get
125 = 59 x 2 + 7
We consider the new divisor 59 and the new remainder 7,and apply the division lemma to get
59 = 7 x 8 + 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 434 and 67145 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(59,7) = HCF(125,59) = HCF(309,125) = HCF(434,309) = HCF(67145,434) .
