HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 746, 129 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 746, 129 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 746, 129 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 746, 129 is 1.
HCF(746, 129) = 1
HCF of 746, 129 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 746, 129 is 1.
Highest Common Factor of 746,129 is 1
Step 1: Since 746 > 129, we apply the division lemma to 746 and 129, to get
746 = 129 x 5 + 101
Step 2: Since the reminder 129 ≠ 0, we apply division lemma to 101 and 129, to get
129 = 101 x 1 + 28
Step 3: We consider the new divisor 101 and the new remainder 28, and apply the division lemma to get
101 = 28 x 3 + 17
We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get
28 = 17 x 1 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 746 and 129 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(101,28) = HCF(129,101) = HCF(746,129) .
