HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 741, 949, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 741, 949, 86 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 741, 949, 86 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 741, 949, 86 is 1.
HCF(741, 949, 86) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 741, 949, 86 is 1.
Step 1: Since 949 > 741, we apply the division lemma to 949 and 741, to get
949 = 741 x 1 + 208
Step 2: Since the reminder 741 ≠ 0, we apply division lemma to 208 and 741, to get
741 = 208 x 3 + 117
Step 3: We consider the new divisor 208 and the new remainder 117, and apply the division lemma to get
208 = 117 x 1 + 91
We consider the new divisor 117 and the new remainder 91,and apply the division lemma to get
117 = 91 x 1 + 26
We consider the new divisor 91 and the new remainder 26,and apply the division lemma to get
91 = 26 x 3 + 13
We consider the new divisor 26 and the new remainder 13,and apply the division lemma to get
26 = 13 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 741 and 949 is 13
Notice that 13 = HCF(26,13) = HCF(91,26) = HCF(117,91) = HCF(208,117) = HCF(741,208) = HCF(949,741) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 13, we apply the division lemma to 86 and 13, to get
86 = 13 x 6 + 8
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 8 and 13, to get
13 = 8 x 1 + 5
Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 13 and 86 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(86,13) .
Here are some samples of HCF using Euclid's Algorithm calculations.
