HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 433, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 433, 121 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 433, 121 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 433, 121 is 1.
HCF(433, 121) = 1
HCF of 433, 121 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 433, 121 is 1.
Highest Common Factor of 433,121 is 1
Step 1: Since 433 > 121, we apply the division lemma to 433 and 121, to get
433 = 121 x 3 + 70
Step 2: Since the reminder 121 ≠ 0, we apply division lemma to 70 and 121, to get
121 = 70 x 1 + 51
Step 3: We consider the new divisor 70 and the new remainder 51, and apply the division lemma to get
70 = 51 x 1 + 19
We consider the new divisor 51 and the new remainder 19,and apply the division lemma to get
51 = 19 x 2 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 433 and 121 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(51,19) = HCF(70,51) = HCF(121,70) = HCF(433,121) .
