HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 909, 569 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 909, 569 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, 909, 569 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, 909, 569 is 1.
HCF(557, 909, 569) = 1
HCF of 557, 909, 569 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, 909, 569 is 1.
Highest Common Factor of 557,909,569 is 1
Step 1: Since 909 > 557, we apply the division lemma to 909 and 557, to get
909 = 557 x 1 + 352
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 352 and 557, to get
557 = 352 x 1 + 205
Step 3: We consider the new divisor 352 and the new remainder 205, and apply the division lemma to get
352 = 205 x 1 + 147
We consider the new divisor 205 and the new remainder 147,and apply the division lemma to get
205 = 147 x 1 + 58
We consider the new divisor 147 and the new remainder 58,and apply the division lemma to get
147 = 58 x 2 + 31
We consider the new divisor 58 and the new remainder 31,and apply the division lemma to get
58 = 31 x 1 + 27
We consider the new divisor 31 and the new remainder 27,and apply the division lemma to get
31 = 27 x 1 + 4
We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get
27 = 4 x 6 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
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 557 and 909 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(31,27) = HCF(58,31) = HCF(147,58) = HCF(205,147) = HCF(352,205) = HCF(557,352) = HCF(909,557) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 569 > 1, we apply the division lemma to 569 and 1, to get
569 = 1 x 569 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 569 is 1
Notice that 1 = HCF(569,1) .
