HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 303, 787, 908 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 303, 787, 908 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 303, 787, 908 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 303, 787, 908 is 1.
HCF(303, 787, 908) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 303, 787, 908 is 1.
Step 1: Since 787 > 303, we apply the division lemma to 787 and 303, to get
787 = 303 x 2 + 181
Step 2: Since the reminder 303 ≠ 0, we apply division lemma to 181 and 303, to get
303 = 181 x 1 + 122
Step 3: We consider the new divisor 181 and the new remainder 122, and apply the division lemma to get
181 = 122 x 1 + 59
We consider the new divisor 122 and the new remainder 59,and apply the division lemma to get
122 = 59 x 2 + 4
We consider the new divisor 59 and the new remainder 4,and apply the division lemma to get
59 = 4 x 14 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 303 and 787 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(59,4) = HCF(122,59) = HCF(181,122) = HCF(303,181) = HCF(787,303) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 908 > 1, we apply the division lemma to 908 and 1, to get
908 = 1 x 908 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 908 is 1
Notice that 1 = HCF(908,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
