HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 901, 255, 620 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 901, 255, 620 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 901, 255, 620 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 901, 255, 620 is 1.
HCF(901, 255, 620) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 901, 255, 620 is 1.
Step 1: Since 901 > 255, we apply the division lemma to 901 and 255, to get
901 = 255 x 3 + 136
Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 136 and 255, to get
255 = 136 x 1 + 119
Step 3: We consider the new divisor 136 and the new remainder 119, and apply the division lemma to get
136 = 119 x 1 + 17
We consider the new divisor 119 and the new remainder 17, and apply the division lemma to get
119 = 17 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 901 and 255 is 17
Notice that 17 = HCF(119,17) = HCF(136,119) = HCF(255,136) = HCF(901,255) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 620 > 17, we apply the division lemma to 620 and 17, to get
620 = 17 x 36 + 8
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 8 and 17, to get
17 = 8 x 2 + 1
Step 3: We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 620 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(620,17) .
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 901, 255, 620?
Answer: HCF of 901, 255, 620 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 901, 255, 620 using Euclid's Algorithm?
Answer: For arbitrary numbers 901, 255, 620 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
