HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 256, 916, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 256, 916, 471 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 256, 916, 471 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 256, 916, 471 is 1.
HCF(256, 916, 471) = 1
HCF of 256, 916, 471 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 256, 916, 471 is 1.
Highest Common Factor of 256,916,471 is 1
Step 1: Since 916 > 256, we apply the division lemma to 916 and 256, to get
916 = 256 x 3 + 148
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 148 and 256, to get
256 = 148 x 1 + 108
Step 3: We consider the new divisor 148 and the new remainder 108, and apply the division lemma to get
148 = 108 x 1 + 40
We consider the new divisor 108 and the new remainder 40,and apply the division lemma to get
108 = 40 x 2 + 28
We consider the new divisor 40 and the new remainder 28,and apply the division lemma to get
40 = 28 x 1 + 12
We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get
28 = 12 x 2 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 256 and 916 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(40,28) = HCF(108,40) = HCF(148,108) = HCF(256,148) = HCF(916,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 471 > 4, we apply the division lemma to 471 and 4, to get
471 = 4 x 117 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 471 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(471,4) .
