HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 703, 205, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 703, 205, 309 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 703, 205, 309 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 703, 205, 309 is 1.
HCF(703, 205, 309) = 1
HCF of 703, 205, 309 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 703, 205, 309 is 1.
Highest Common Factor of 703,205,309 is 1
Step 1: Since 703 > 205, we apply the division lemma to 703 and 205, to get
703 = 205 x 3 + 88
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 88 and 205, to get
205 = 88 x 2 + 29
Step 3: We consider the new divisor 88 and the new remainder 29, and apply the division lemma to get
88 = 29 x 3 + 1
We consider the new divisor 29 and the new remainder 1, and apply the division lemma to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 703 and 205 is 1
Notice that 1 = HCF(29,1) = HCF(88,29) = HCF(205,88) = HCF(703,205) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 309 > 1, we apply the division lemma to 309 and 1, to get
309 = 1 x 309 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 309 is 1
Notice that 1 = HCF(309,1) .
