HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 900 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 900 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 493, 900 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 493, 900 is 1.
HCF(493, 900) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 900 is 1.
Step 1: Since 900 > 493, we apply the division lemma to 900 and 493, to get
900 = 493 x 1 + 407
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 407 and 493, to get
493 = 407 x 1 + 86
Step 3: We consider the new divisor 407 and the new remainder 86, and apply the division lemma to get
407 = 86 x 4 + 63
We consider the new divisor 86 and the new remainder 63,and apply the division lemma to get
86 = 63 x 1 + 23
We consider the new divisor 63 and the new remainder 23,and apply the division lemma to get
63 = 23 x 2 + 17
We consider the new divisor 23 and the new remainder 17,and apply the division lemma to get
23 = 17 x 1 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 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 493 and 900 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(23,17) = HCF(63,23) = HCF(86,63) = HCF(407,86) = HCF(493,407) = HCF(900,493) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 493, 900?
Answer: HCF of 493, 900 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 493, 900 using Euclid's Algorithm?
Answer: For arbitrary numbers 493, 900 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
