HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 235, 361, 442, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 235, 361, 442, 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 235, 361, 442, 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 235, 361, 442, 203 is 1.
HCF(235, 361, 442, 203) = 1
HCF of 235, 361, 442, 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 235, 361, 442, 203 is 1.
Highest Common Factor of 235,361,442,203 is 1
Step 1: Since 361 > 235, we apply the division lemma to 361 and 235, to get
361 = 235 x 1 + 126
Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 126 and 235, to get
235 = 126 x 1 + 109
Step 3: We consider the new divisor 126 and the new remainder 109, and apply the division lemma to get
126 = 109 x 1 + 17
We consider the new divisor 109 and the new remainder 17,and apply the division lemma to get
109 = 17 x 6 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 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 235 and 361 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(109,17) = HCF(126,109) = HCF(235,126) = HCF(361,235) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 442 > 1, we apply the division lemma to 442 and 1, to get
442 = 1 x 442 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 442 is 1
Notice that 1 = HCF(442,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 203 > 1, we apply the division lemma to 203 and 1, to get
203 = 1 x 203 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 203 is 1
Notice that 1 = HCF(203,1) .
