HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 358, 493, 772 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 358, 493, 772 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 358, 493, 772 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 358, 493, 772 is 1.
HCF(358, 493, 772) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 358, 493, 772 is 1.
Step 1: Since 493 > 358, we apply the division lemma to 493 and 358, to get
493 = 358 x 1 + 135
Step 2: Since the reminder 358 ≠ 0, we apply division lemma to 135 and 358, to get
358 = 135 x 2 + 88
Step 3: We consider the new divisor 135 and the new remainder 88, and apply the division lemma to get
135 = 88 x 1 + 47
We consider the new divisor 88 and the new remainder 47,and apply the division lemma to get
88 = 47 x 1 + 41
We consider the new divisor 47 and the new remainder 41,and apply the division lemma to get
47 = 41 x 1 + 6
We consider the new divisor 41 and the new remainder 6,and apply the division lemma to get
41 = 6 x 6 + 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 358 and 493 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(41,6) = HCF(47,41) = HCF(88,47) = HCF(135,88) = HCF(358,135) = HCF(493,358) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 772 > 1, we apply the division lemma to 772 and 1, to get
772 = 1 x 772 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 772 is 1
Notice that 1 = HCF(772,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 358, 493, 772?
Answer: HCF of 358, 493, 772 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 358, 493, 772 using Euclid's Algorithm?
Answer: For arbitrary numbers 358, 493, 772 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
