HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1703, 703 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1703, 703 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 1703, 703 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 1703, 703 is 1.
HCF(1703, 703) = 1
HCF of 1703, 703 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1703, 703 is 1.
Highest Common Factor of 1703,703 is 1
Step 1: Since 1703 > 703, we apply the division lemma to 1703 and 703, to get
1703 = 703 x 2 + 297
Step 2: Since the reminder 703 ≠ 0, we apply division lemma to 297 and 703, to get
703 = 297 x 2 + 109
Step 3: We consider the new divisor 297 and the new remainder 109, and apply the division lemma to get
297 = 109 x 2 + 79
We consider the new divisor 109 and the new remainder 79,and apply the division lemma to get
109 = 79 x 1 + 30
We consider the new divisor 79 and the new remainder 30,and apply the division lemma to get
79 = 30 x 2 + 19
We consider the new divisor 30 and the new remainder 19,and apply the division lemma to get
30 = 19 x 1 + 11
We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get
19 = 11 x 1 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 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 1703 and 703 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(30,19) = HCF(79,30) = HCF(109,79) = HCF(297,109) = HCF(703,297) = HCF(1703,703) .
