HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 940, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 354, 940, 475 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 354, 940, 475 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 354, 940, 475 is 1.
HCF(354, 940, 475) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 354, 940, 475 is 1.
Step 1: Since 940 > 354, we apply the division lemma to 940 and 354, to get
940 = 354 x 2 + 232
Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 232 and 354, to get
354 = 232 x 1 + 122
Step 3: We consider the new divisor 232 and the new remainder 122, and apply the division lemma to get
232 = 122 x 1 + 110
We consider the new divisor 122 and the new remainder 110,and apply the division lemma to get
122 = 110 x 1 + 12
We consider the new divisor 110 and the new remainder 12,and apply the division lemma to get
110 = 12 x 9 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 354 and 940 is 2
Notice that 2 = HCF(12,2) = HCF(110,12) = HCF(122,110) = HCF(232,122) = HCF(354,232) = HCF(940,354) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 475 > 2, we apply the division lemma to 475 and 2, to get
475 = 2 x 237 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 475 is 1
Notice that 1 = HCF(2,1) = HCF(475,2) .
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 354, 940, 475?
Answer: HCF of 354, 940, 475 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 354, 940, 475 using Euclid's Algorithm?
Answer: For arbitrary numbers 354, 940, 475 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
