HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 129, 869, 752 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 129, 869, 752 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 129, 869, 752 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 129, 869, 752 is 1.
HCF(129, 869, 752) = 1
HCF of 129, 869, 752 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 129, 869, 752 is 1.
Highest Common Factor of 129,869,752 is 1
Step 1: Since 869 > 129, we apply the division lemma to 869 and 129, to get
869 = 129 x 6 + 95
Step 2: Since the reminder 129 ≠ 0, we apply division lemma to 95 and 129, to get
129 = 95 x 1 + 34
Step 3: We consider the new divisor 95 and the new remainder 34, and apply the division lemma to get
95 = 34 x 2 + 27
We consider the new divisor 34 and the new remainder 27,and apply the division lemma to get
34 = 27 x 1 + 7
We consider the new divisor 27 and the new remainder 7,and apply the division lemma to get
27 = 7 x 3 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 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 129 and 869 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(27,7) = HCF(34,27) = HCF(95,34) = HCF(129,95) = HCF(869,129) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 752 > 1, we apply the division lemma to 752 and 1, to get
752 = 1 x 752 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 752 is 1
Notice that 1 = HCF(752,1) .
