HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 238 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 238 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 620, 238 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 620, 238 is 2.
HCF(620, 238) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 238 is 2.
Step 1: Since 620 > 238, we apply the division lemma to 620 and 238, to get
620 = 238 x 2 + 144
Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 144 and 238, to get
238 = 144 x 1 + 94
Step 3: We consider the new divisor 144 and the new remainder 94, and apply the division lemma to get
144 = 94 x 1 + 50
We consider the new divisor 94 and the new remainder 50,and apply the division lemma to get
94 = 50 x 1 + 44
We consider the new divisor 50 and the new remainder 44,and apply the division lemma to get
50 = 44 x 1 + 6
We consider the new divisor 44 and the new remainder 6,and apply the division lemma to get
44 = 6 x 7 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 620 and 238 is 2
Notice that 2 = HCF(6,2) = HCF(44,6) = HCF(50,44) = HCF(94,50) = HCF(144,94) = HCF(238,144) = HCF(620,238) .
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 620, 238?
Answer: HCF of 620, 238 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 620, 238 using Euclid's Algorithm?
Answer: For arbitrary numbers 620, 238 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
