HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 712, 996, 139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 712, 996, 139 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 712, 996, 139 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 712, 996, 139 is 1.
HCF(712, 996, 139) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 712, 996, 139 is 1.
Step 1: Since 996 > 712, we apply the division lemma to 996 and 712, to get
996 = 712 x 1 + 284
Step 2: Since the reminder 712 ≠ 0, we apply division lemma to 284 and 712, to get
712 = 284 x 2 + 144
Step 3: We consider the new divisor 284 and the new remainder 144, and apply the division lemma to get
284 = 144 x 1 + 140
We consider the new divisor 144 and the new remainder 140,and apply the division lemma to get
144 = 140 x 1 + 4
We consider the new divisor 140 and the new remainder 4,and apply the division lemma to get
140 = 4 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 712 and 996 is 4
Notice that 4 = HCF(140,4) = HCF(144,140) = HCF(284,144) = HCF(712,284) = HCF(996,712) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 139 > 4, we apply the division lemma to 139 and 4, to get
139 = 4 x 34 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 139 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(139,4) .
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 712, 996, 139?
Answer: HCF of 712, 996, 139 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 712, 996, 139 using Euclid's Algorithm?
Answer: For arbitrary numbers 712, 996, 139 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
