HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 993, 429 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 993, 429 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 620, 993, 429 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, 993, 429 is 1.
HCF(620, 993, 429) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 993, 429 is 1.
Step 1: Since 993 > 620, we apply the division lemma to 993 and 620, to get
993 = 620 x 1 + 373
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 373 and 620, to get
620 = 373 x 1 + 247
Step 3: We consider the new divisor 373 and the new remainder 247, and apply the division lemma to get
373 = 247 x 1 + 126
We consider the new divisor 247 and the new remainder 126,and apply the division lemma to get
247 = 126 x 1 + 121
We consider the new divisor 126 and the new remainder 121,and apply the division lemma to get
126 = 121 x 1 + 5
We consider the new divisor 121 and the new remainder 5,and apply the division lemma to get
121 = 5 x 24 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 620 and 993 is 1
Notice that 1 = HCF(5,1) = HCF(121,5) = HCF(126,121) = HCF(247,126) = HCF(373,247) = HCF(620,373) = HCF(993,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 429 > 1, we apply the division lemma to 429 and 1, to get
429 = 1 x 429 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 429 is 1
Notice that 1 = HCF(429,1) .
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, 993, 429?
Answer: HCF of 620, 993, 429 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 620, 993, 429 using Euclid's Algorithm?
Answer: For arbitrary numbers 620, 993, 429 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
