HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 121, 799 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 121, 799 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 121, 799 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 121, 799 is 1.
HCF(121, 799) = 1
HCF of 121, 799 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 121, 799 is 1.
Highest Common Factor of 121,799 is 1
Step 1: Since 799 > 121, we apply the division lemma to 799 and 121, to get
799 = 121 x 6 + 73
Step 2: Since the reminder 121 ≠ 0, we apply division lemma to 73 and 121, to get
121 = 73 x 1 + 48
Step 3: We consider the new divisor 73 and the new remainder 48, and apply the division lemma to get
73 = 48 x 1 + 25
We consider the new divisor 48 and the new remainder 25,and apply the division lemma to get
48 = 25 x 1 + 23
We consider the new divisor 25 and the new remainder 23,and apply the division lemma to get
25 = 23 x 1 + 2
We consider the new divisor 23 and the new remainder 2,and apply the division lemma to get
23 = 2 x 11 + 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 121 and 799 is 1
Notice that 1 = HCF(2,1) = HCF(23,2) = HCF(25,23) = HCF(48,25) = HCF(73,48) = HCF(121,73) = HCF(799,121) .
