HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 3685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 3685 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, 3685 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, 3685 is 1.
HCF(189, 3685) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 3685 is 1.
Step 1: Since 3685 > 189, we apply the division lemma to 3685 and 189, to get
3685 = 189 x 19 + 94
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 94 and 189, to get
189 = 94 x 2 + 1
Step 3: We consider the new divisor 94 and the new remainder 1, and apply the division lemma to get
94 = 1 x 94 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 189 and 3685 is 1
Notice that 1 = HCF(94,1) = HCF(189,94) = HCF(3685,189) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 189, 3685?
Answer: HCF of 189, 3685 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 189, 3685 using Euclid's Algorithm?
Answer: For arbitrary numbers 189, 3685 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
