HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 290, 817 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 730, 290, 817 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, 290, 817 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, 290, 817 is 1.
HCF(730, 290, 817) = 1
HCF of 730, 290, 817 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, 290, 817 is 1.
Highest Common Factor of 730,290,817 is 1
Step 1: Since 730 > 290, we apply the division lemma to 730 and 290, to get
730 = 290 x 2 + 150
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 150 and 290, to get
290 = 150 x 1 + 140
Step 3: We consider the new divisor 150 and the new remainder 140, and apply the division lemma to get
150 = 140 x 1 + 10
We consider the new divisor 140 and the new remainder 10, and apply the division lemma to get
140 = 10 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 730 and 290 is 10
Notice that 10 = HCF(140,10) = HCF(150,140) = HCF(290,150) = HCF(730,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 817 > 10, we apply the division lemma to 817 and 10, to get
817 = 10 x 81 + 7
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 7 and 10, to get
10 = 7 x 1 + 3
Step 3: We consider the new divisor 7 and the new remainder 3, and apply the division lemma to get
7 = 3 x 2 + 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 10 and 817 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(817,10) .
