HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7802, 660 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 7802, 660 is 2 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 7802, 660 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 7802, 660 is 2.
HCF(7802, 660) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7802, 660 is 2.
Step 1: Since 7802 > 660, we apply the division lemma to 7802 and 660, to get
7802 = 660 x 11 + 542
Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 542 and 660, to get
660 = 542 x 1 + 118
Step 3: We consider the new divisor 542 and the new remainder 118, and apply the division lemma to get
542 = 118 x 4 + 70
We consider the new divisor 118 and the new remainder 70,and apply the division lemma to get
118 = 70 x 1 + 48
We consider the new divisor 70 and the new remainder 48,and apply the division lemma to get
70 = 48 x 1 + 22
We consider the new divisor 48 and the new remainder 22,and apply the division lemma to get
48 = 22 x 2 + 4
We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get
22 = 4 x 5 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 7802 and 660 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(48,22) = HCF(70,48) = HCF(118,70) = HCF(542,118) = HCF(660,542) = HCF(7802,660) .
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 7802, 660?
Answer: HCF of 7802, 660 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 7802, 660 using Euclid's Algorithm?
Answer: For arbitrary numbers 7802, 660 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
