HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 399, 1893 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 399, 1893 is 3 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 399, 1893 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 399, 1893 is 3.
HCF(399, 1893) = 3
HCF of 399, 1893 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 399, 1893 is 3.
Highest Common Factor of 399,1893 is 3
Step 1: Since 1893 > 399, we apply the division lemma to 1893 and 399, to get
1893 = 399 x 4 + 297
Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 297 and 399, to get
399 = 297 x 1 + 102
Step 3: We consider the new divisor 297 and the new remainder 102, and apply the division lemma to get
297 = 102 x 2 + 93
We consider the new divisor 102 and the new remainder 93,and apply the division lemma to get
102 = 93 x 1 + 9
We consider the new divisor 93 and the new remainder 9,and apply the division lemma to get
93 = 9 x 10 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 399 and 1893 is 3
Notice that 3 = HCF(9,3) = HCF(93,9) = HCF(102,93) = HCF(297,102) = HCF(399,297) = HCF(1893,399) .
