HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 403, 917, 152 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 403, 917, 152 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 403, 917, 152 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 403, 917, 152 is 1.
HCF(403, 917, 152) = 1
HCF of 403, 917, 152 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 403, 917, 152 is 1.
Highest Common Factor of 403,917,152 is 1
Step 1: Since 917 > 403, we apply the division lemma to 917 and 403, to get
917 = 403 x 2 + 111
Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 111 and 403, to get
403 = 111 x 3 + 70
Step 3: We consider the new divisor 111 and the new remainder 70, and apply the division lemma to get
111 = 70 x 1 + 41
We consider the new divisor 70 and the new remainder 41,and apply the division lemma to get
70 = 41 x 1 + 29
We consider the new divisor 41 and the new remainder 29,and apply the division lemma to get
41 = 29 x 1 + 12
We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get
29 = 12 x 2 + 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 403 and 917 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(41,29) = HCF(70,41) = HCF(111,70) = HCF(403,111) = HCF(917,403) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 152 > 1, we apply the division lemma to 152 and 1, to get
152 = 1 x 152 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 152 is 1
Notice that 1 = HCF(152,1) .
