HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 904 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 904 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 189, 904 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 189, 904 is 1.
HCF(189, 904) = 1
HCF of 189, 904 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 904 is 1.
Highest Common Factor of 189,904 is 1
Step 1: Since 904 > 189, we apply the division lemma to 904 and 189, to get
904 = 189 x 4 + 148
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 148 and 189, to get
189 = 148 x 1 + 41
Step 3: We consider the new divisor 148 and the new remainder 41, and apply the division lemma to get
148 = 41 x 3 + 25
We consider the new divisor 41 and the new remainder 25,and apply the division lemma to get
41 = 25 x 1 + 16
We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get
25 = 16 x 1 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 189 and 904 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(41,25) = HCF(148,41) = HCF(189,148) = HCF(904,189) .
