HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 232, 22 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 232, 22 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 625, 232, 22 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 625, 232, 22 is 1.
HCF(625, 232, 22) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 625, 232, 22 is 1.
Step 1: Since 625 > 232, we apply the division lemma to 625 and 232, to get
625 = 232 x 2 + 161
Step 2: Since the reminder 232 ≠ 0, we apply division lemma to 161 and 232, to get
232 = 161 x 1 + 71
Step 3: We consider the new divisor 161 and the new remainder 71, and apply the division lemma to get
161 = 71 x 2 + 19
We consider the new divisor 71 and the new remainder 19,and apply the division lemma to get
71 = 19 x 3 + 14
We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get
19 = 14 x 1 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 625 and 232 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(71,19) = HCF(161,71) = HCF(232,161) = HCF(625,232) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1
Notice that 1 = HCF(22,1) .
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 625, 232, 22?
Answer: HCF of 625, 232, 22 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 625, 232, 22 using Euclid's Algorithm?
Answer: For arbitrary numbers 625, 232, 22 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
