HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 757, 479, 75 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 471, 757, 479, 75 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 471, 757, 479, 75 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 471, 757, 479, 75 is 1.
HCF(471, 757, 479, 75) = 1
HCF of 471, 757, 479, 75 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 471, 757, 479, 75 is 1.
Highest Common Factor of 471,757,479,75 is 1
Step 1: Since 757 > 471, we apply the division lemma to 757 and 471, to get
757 = 471 x 1 + 286
Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 286 and 471, to get
471 = 286 x 1 + 185
Step 3: We consider the new divisor 286 and the new remainder 185, and apply the division lemma to get
286 = 185 x 1 + 101
We consider the new divisor 185 and the new remainder 101,and apply the division lemma to get
185 = 101 x 1 + 84
We consider the new divisor 101 and the new remainder 84,and apply the division lemma to get
101 = 84 x 1 + 17
We consider the new divisor 84 and the new remainder 17,and apply the division lemma to get
84 = 17 x 4 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 471 and 757 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(84,17) = HCF(101,84) = HCF(185,101) = HCF(286,185) = HCF(471,286) = HCF(757,471) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 479 > 1, we apply the division lemma to 479 and 1, to get
479 = 1 x 479 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 479 is 1
Notice that 1 = HCF(479,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 75 > 1, we apply the division lemma to 75 and 1, to get
75 = 1 x 75 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 75 is 1
Notice that 1 = HCF(75,1) .
