HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 666 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 126, 666 is 18 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 126, 666 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 126, 666 is 18.
HCF(126, 666) = 18
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 126, 666 is 18.
Step 1: Since 666 > 126, we apply the division lemma to 666 and 126, to get
666 = 126 x 5 + 36
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 36 and 126, to get
126 = 36 x 3 + 18
Step 3: We consider the new divisor 36 and the new remainder 18, and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 126 and 666 is 18
Notice that 18 = HCF(36,18) = HCF(126,36) = HCF(666,126) .
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 126, 666?
Answer: HCF of 126, 666 is 18 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 126, 666 using Euclid's Algorithm?
Answer: For arbitrary numbers 126, 666 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
