HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 354, 203 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 354, 203 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 354, 203 is 1.
HCF(354, 203) = 1
HCF of 354, 203 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 354, 203 is 1.
Highest Common Factor of 354,203 is 1
Step 1: Since 354 > 203, we apply the division lemma to 354 and 203, to get
354 = 203 x 1 + 151
Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 151 and 203, to get
203 = 151 x 1 + 52
Step 3: We consider the new divisor 151 and the new remainder 52, and apply the division lemma to get
151 = 52 x 2 + 47
We consider the new divisor 52 and the new remainder 47,and apply the division lemma to get
52 = 47 x 1 + 5
We consider the new divisor 47 and the new remainder 5,and apply the division lemma to get
47 = 5 x 9 + 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 354 and 203 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(47,5) = HCF(52,47) = HCF(151,52) = HCF(203,151) = HCF(354,203) .
