HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 133, 237 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 133, 237 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 133, 237 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 133, 237 is 1.
HCF(133, 237) = 1
HCF of 133, 237 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 133, 237 is 1.
Highest Common Factor of 133,237 is 1
Step 1: Since 237 > 133, we apply the division lemma to 237 and 133, to get
237 = 133 x 1 + 104
Step 2: Since the reminder 133 ≠ 0, we apply division lemma to 104 and 133, to get
133 = 104 x 1 + 29
Step 3: We consider the new divisor 104 and the new remainder 29, and apply the division lemma to get
104 = 29 x 3 + 17
We consider the new divisor 29 and the new remainder 17,and apply the division lemma to get
29 = 17 x 1 + 12
We consider the new divisor 17 and the new remainder 12,and apply the division lemma to get
17 = 12 x 1 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 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 133 and 237 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(29,17) = HCF(104,29) = HCF(133,104) = HCF(237,133) .
