HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1972, 5723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1972, 5723 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 1972, 5723 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 1972, 5723 is 1.
HCF(1972, 5723) = 1
HCF of 1972, 5723 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1972, 5723 is 1.
Highest Common Factor of 1972,5723 is 1
Step 1: Since 5723 > 1972, we apply the division lemma to 5723 and 1972, to get
5723 = 1972 x 2 + 1779
Step 2: Since the reminder 1972 ≠ 0, we apply division lemma to 1779 and 1972, to get
1972 = 1779 x 1 + 193
Step 3: We consider the new divisor 1779 and the new remainder 193, and apply the division lemma to get
1779 = 193 x 9 + 42
We consider the new divisor 193 and the new remainder 42,and apply the division lemma to get
193 = 42 x 4 + 25
We consider the new divisor 42 and the new remainder 25,and apply the division lemma to get
42 = 25 x 1 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1972 and 5723 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(42,25) = HCF(193,42) = HCF(1779,193) = HCF(1972,1779) = HCF(5723,1972) .
