HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 705, 353, 772 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 705, 353, 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 297, 705, 353, 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 297, 705, 353, 772 is 1.
HCF(297, 705, 353, 772) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 705, 353, 772 is 1.
Step 1: Since 705 > 297, we apply the division lemma to 705 and 297, to get
705 = 297 x 2 + 111
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 111 and 297, to get
297 = 111 x 2 + 75
Step 3: We consider the new divisor 111 and the new remainder 75, and apply the division lemma to get
111 = 75 x 1 + 36
We consider the new divisor 75 and the new remainder 36,and apply the division lemma to get
75 = 36 x 2 + 3
We consider the new divisor 36 and the new remainder 3,and apply the division lemma to get
36 = 3 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 297 and 705 is 3
Notice that 3 = HCF(36,3) = HCF(75,36) = HCF(111,75) = HCF(297,111) = HCF(705,297) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 353 > 3, we apply the division lemma to 353 and 3, to get
353 = 3 x 117 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 353 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(353,3) .
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.
