HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 1395 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 1395 is 9 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, 1395 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, 1395 is 9.
HCF(189, 1395) = 9
HCF of 189, 1395 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, 1395 is 9.
Highest Common Factor of 189,1395 is 9
Step 1: Since 1395 > 189, we apply the division lemma to 1395 and 189, to get
1395 = 189 x 7 + 72
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 72 and 189, to get
189 = 72 x 2 + 45
Step 3: We consider the new divisor 72 and the new remainder 45, and apply the division lemma to get
72 = 45 x 1 + 27
We consider the new divisor 45 and the new remainder 27,and apply the division lemma to get
45 = 27 x 1 + 18
We consider the new divisor 27 and the new remainder 18,and apply the division lemma to get
27 = 18 x 1 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 189 and 1395 is 9
Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(45,27) = HCF(72,45) = HCF(189,72) = HCF(1395,189) .
