HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 94, 731 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 94, 731 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 705, 94, 731 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 705, 94, 731 is 1.
HCF(705, 94, 731) = 1
HCF of 705, 94, 731 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 94, 731 is 1.
Highest Common Factor of 705,94,731 is 1
Step 1: Since 705 > 94, we apply the division lemma to 705 and 94, to get
705 = 94 x 7 + 47
Step 2: Since the reminder 94 ≠ 0, we apply division lemma to 47 and 94, to get
94 = 47 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 47, the HCF of 705 and 94 is 47
Notice that 47 = HCF(94,47) = HCF(705,94) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 731 > 47, we apply the division lemma to 731 and 47, to get
731 = 47 x 15 + 26
Step 2: Since the reminder 47 ≠ 0, we apply division lemma to 26 and 47, to get
47 = 26 x 1 + 21
Step 3: We consider the new divisor 26 and the new remainder 21, and apply the division lemma to get
26 = 21 x 1 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 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 47 and 731 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(47,26) = HCF(731,47) .
