HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 354 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 845, 354 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 845, 354 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 845, 354 is 1.
HCF(845, 354) = 1
HCF of 845, 354 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 845, 354 is 1.
Highest Common Factor of 845,354 is 1
Step 1: Since 845 > 354, we apply the division lemma to 845 and 354, to get
845 = 354 x 2 + 137
Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 137 and 354, to get
354 = 137 x 2 + 80
Step 3: We consider the new divisor 137 and the new remainder 80, and apply the division lemma to get
137 = 80 x 1 + 57
We consider the new divisor 80 and the new remainder 57,and apply the division lemma to get
80 = 57 x 1 + 23
We consider the new divisor 57 and the new remainder 23,and apply the division lemma to get
57 = 23 x 2 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 845 and 354 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(57,23) = HCF(80,57) = HCF(137,80) = HCF(354,137) = HCF(845,354) .
