HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 447, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 730, 447, 91 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 730, 447, 91 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 730, 447, 91 is 1.
HCF(730, 447, 91) = 1
HCF of 730, 447, 91 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 730, 447, 91 is 1.
Highest Common Factor of 730,447,91 is 1
Step 1: Since 730 > 447, we apply the division lemma to 730 and 447, to get
730 = 447 x 1 + 283
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 283 and 447, to get
447 = 283 x 1 + 164
Step 3: We consider the new divisor 283 and the new remainder 164, and apply the division lemma to get
283 = 164 x 1 + 119
We consider the new divisor 164 and the new remainder 119,and apply the division lemma to get
164 = 119 x 1 + 45
We consider the new divisor 119 and the new remainder 45,and apply the division lemma to get
119 = 45 x 2 + 29
We consider the new divisor 45 and the new remainder 29,and apply the division lemma to get
45 = 29 x 1 + 16
We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get
29 = 16 x 1 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 730 and 447 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(45,29) = HCF(119,45) = HCF(164,119) = HCF(283,164) = HCF(447,283) = HCF(730,447) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1
Notice that 1 = HCF(91,1) .
