HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 768, 950 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 768, 950 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 557, 768, 950 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 557, 768, 950 is 1.
HCF(557, 768, 950) = 1
HCF of 557, 768, 950 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 557, 768, 950 is 1.
Highest Common Factor of 557,768,950 is 1
Step 1: Since 768 > 557, we apply the division lemma to 768 and 557, to get
768 = 557 x 1 + 211
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 211 and 557, to get
557 = 211 x 2 + 135
Step 3: We consider the new divisor 211 and the new remainder 135, and apply the division lemma to get
211 = 135 x 1 + 76
We consider the new divisor 135 and the new remainder 76,and apply the division lemma to get
135 = 76 x 1 + 59
We consider the new divisor 76 and the new remainder 59,and apply the division lemma to get
76 = 59 x 1 + 17
We consider the new divisor 59 and the new remainder 17,and apply the division lemma to get
59 = 17 x 3 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 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 557 and 768 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(59,17) = HCF(76,59) = HCF(135,76) = HCF(211,135) = HCF(557,211) = HCF(768,557) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 950 > 1, we apply the division lemma to 950 and 1, to get
950 = 1 x 950 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 950 is 1
Notice that 1 = HCF(950,1) .
