HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 950, 47 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 950, 47 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 657, 950, 47 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 657, 950, 47 is 1.
HCF(657, 950, 47) = 1
HCF of 657, 950, 47 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 657, 950, 47 is 1.
Highest Common Factor of 657,950,47 is 1
Step 1: Since 950 > 657, we apply the division lemma to 950 and 657, to get
950 = 657 x 1 + 293
Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 293 and 657, to get
657 = 293 x 2 + 71
Step 3: We consider the new divisor 293 and the new remainder 71, and apply the division lemma to get
293 = 71 x 4 + 9
We consider the new divisor 71 and the new remainder 9,and apply the division lemma to get
71 = 9 x 7 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 657 and 950 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(71,9) = HCF(293,71) = HCF(657,293) = HCF(950,657) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 47 > 1, we apply the division lemma to 47 and 1, to get
47 = 1 x 47 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 47 is 1
Notice that 1 = HCF(47,1) .
