HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 516, 749, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 516, 749, 57 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 516, 749, 57 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 516, 749, 57 is 1.
HCF(516, 749, 57) = 1
HCF of 516, 749, 57 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 516, 749, 57 is 1.
Highest Common Factor of 516,749,57 is 1
Step 1: Since 749 > 516, we apply the division lemma to 749 and 516, to get
749 = 516 x 1 + 233
Step 2: Since the reminder 516 ≠ 0, we apply division lemma to 233 and 516, to get
516 = 233 x 2 + 50
Step 3: We consider the new divisor 233 and the new remainder 50, and apply the division lemma to get
233 = 50 x 4 + 33
We consider the new divisor 50 and the new remainder 33,and apply the division lemma to get
50 = 33 x 1 + 17
We consider the new divisor 33 and the new remainder 17,and apply the division lemma to get
33 = 17 x 1 + 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 516 and 749 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(33,17) = HCF(50,33) = HCF(233,50) = HCF(516,233) = HCF(749,516) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get
57 = 1 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1
Notice that 1 = HCF(57,1) .
