HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 901, 711 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 391, 901, 711 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 391, 901, 711 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 391, 901, 711 is 1.
HCF(391, 901, 711) = 1
HCF of 391, 901, 711 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 391, 901, 711 is 1.
Highest Common Factor of 391,901,711 is 1
Step 1: Since 901 > 391, we apply the division lemma to 901 and 391, to get
901 = 391 x 2 + 119
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 119 and 391, to get
391 = 119 x 3 + 34
Step 3: We consider the new divisor 119 and the new remainder 34, and apply the division lemma to get
119 = 34 x 3 + 17
We consider the new divisor 34 and the new remainder 17, and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 391 and 901 is 17
Notice that 17 = HCF(34,17) = HCF(119,34) = HCF(391,119) = HCF(901,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 711 > 17, we apply the division lemma to 711 and 17, to get
711 = 17 x 41 + 14
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 14 and 17, to get
17 = 14 x 1 + 3
Step 3: We consider the new divisor 14 and the new remainder 3, and apply the division lemma to get
14 = 3 x 4 + 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 17 and 711 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(711,17) .
