HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 699 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 942, 699 is 3 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 942, 699 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 942, 699 is 3.
HCF(942, 699) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 942, 699 is 3.
Step 1: Since 942 > 699, we apply the division lemma to 942 and 699, to get
942 = 699 x 1 + 243
Step 2: Since the reminder 699 ≠ 0, we apply division lemma to 243 and 699, to get
699 = 243 x 2 + 213
Step 3: We consider the new divisor 243 and the new remainder 213, and apply the division lemma to get
243 = 213 x 1 + 30
We consider the new divisor 213 and the new remainder 30,and apply the division lemma to get
213 = 30 x 7 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 942 and 699 is 3
Notice that 3 = HCF(30,3) = HCF(213,30) = HCF(243,213) = HCF(699,243) = HCF(942,699) .
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 942, 699?
Answer: HCF of 942, 699 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 942, 699 using Euclid's Algorithm?
Answer: For arbitrary numbers 942, 699 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
