HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1664, 2038 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 1664, 2038 is 2 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 1664, 2038 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 1664, 2038 is 2.
HCF(1664, 2038) = 2
HCF of 1664, 2038 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1664, 2038 is 2.
Highest Common Factor of 1664,2038 is 2
Step 1: Since 2038 > 1664, we apply the division lemma to 2038 and 1664, to get
2038 = 1664 x 1 + 374
Step 2: Since the reminder 1664 ≠ 0, we apply division lemma to 374 and 1664, to get
1664 = 374 x 4 + 168
Step 3: We consider the new divisor 374 and the new remainder 168, and apply the division lemma to get
374 = 168 x 2 + 38
We consider the new divisor 168 and the new remainder 38,and apply the division lemma to get
168 = 38 x 4 + 16
We consider the new divisor 38 and the new remainder 16,and apply the division lemma to get
38 = 16 x 2 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 1664 and 2038 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(38,16) = HCF(168,38) = HCF(374,168) = HCF(1664,374) = HCF(2038,1664) .
