HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 122 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 431, 122 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 431, 122 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 431, 122 is 1.
HCF(431, 122) = 1
HCF of 431, 122 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 431, 122 is 1.
Highest Common Factor of 431,122 is 1
Step 1: Since 431 > 122, we apply the division lemma to 431 and 122, to get
431 = 122 x 3 + 65
Step 2: Since the reminder 122 ≠ 0, we apply division lemma to 65 and 122, to get
122 = 65 x 1 + 57
Step 3: We consider the new divisor 65 and the new remainder 57, and apply the division lemma to get
65 = 57 x 1 + 8
We consider the new divisor 57 and the new remainder 8,and apply the division lemma to get
57 = 8 x 7 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 431 and 122 is 1
Notice that 1 = HCF(8,1) = HCF(57,8) = HCF(65,57) = HCF(122,65) = HCF(431,122) .
