HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1889, 9990 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1889, 9990 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 1889, 9990 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 1889, 9990 is 1.
HCF(1889, 9990) = 1
HCF of 1889, 9990 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1889, 9990 is 1.
Highest Common Factor of 1889,9990 is 1
Step 1: Since 9990 > 1889, we apply the division lemma to 9990 and 1889, to get
9990 = 1889 x 5 + 545
Step 2: Since the reminder 1889 ≠ 0, we apply division lemma to 545 and 1889, to get
1889 = 545 x 3 + 254
Step 3: We consider the new divisor 545 and the new remainder 254, and apply the division lemma to get
545 = 254 x 2 + 37
We consider the new divisor 254 and the new remainder 37,and apply the division lemma to get
254 = 37 x 6 + 32
We consider the new divisor 37 and the new remainder 32,and apply the division lemma to get
37 = 32 x 1 + 5
We consider the new divisor 32 and the new remainder 5,and apply the division lemma to get
32 = 5 x 6 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 1889 and 9990 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(32,5) = HCF(37,32) = HCF(254,37) = HCF(545,254) = HCF(1889,545) = HCF(9990,1889) .
