HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 469, 105, 903 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 718, 469, 105, 903 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 718, 469, 105, 903 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 718, 469, 105, 903 is 1.
HCF(718, 469, 105, 903) = 1
HCF of 718, 469, 105, 903 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 718, 469, 105, 903 is 1.
Highest Common Factor of 718,469,105,903 is 1
Step 1: Since 718 > 469, we apply the division lemma to 718 and 469, to get
718 = 469 x 1 + 249
Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 249 and 469, to get
469 = 249 x 1 + 220
Step 3: We consider the new divisor 249 and the new remainder 220, and apply the division lemma to get
249 = 220 x 1 + 29
We consider the new divisor 220 and the new remainder 29,and apply the division lemma to get
220 = 29 x 7 + 17
We consider the new divisor 29 and the new remainder 17,and apply the division lemma to get
29 = 17 x 1 + 12
We consider the new divisor 17 and the new remainder 12,and apply the division lemma to get
17 = 12 x 1 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
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 718 and 469 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(29,17) = HCF(220,29) = HCF(249,220) = HCF(469,249) = HCF(718,469) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 105 > 1, we apply the division lemma to 105 and 1, to get
105 = 1 x 105 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 105 is 1
Notice that 1 = HCF(105,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 903 > 1, we apply the division lemma to 903 and 1, to get
903 = 1 x 903 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 903 is 1
Notice that 1 = HCF(903,1) .
