HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 285, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 285, 475 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, 285, 475 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, 285, 475 is 1.
HCF(557, 285, 475) = 1
HCF of 557, 285, 475 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, 285, 475 is 1.
Highest Common Factor of 557,285,475 is 1
Step 1: Since 557 > 285, we apply the division lemma to 557 and 285, to get
557 = 285 x 1 + 272
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 272 and 285, to get
285 = 272 x 1 + 13
Step 3: We consider the new divisor 272 and the new remainder 13, and apply the division lemma to get
272 = 13 x 20 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 285 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(272,13) = HCF(285,272) = HCF(557,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 475 > 1, we apply the division lemma to 475 and 1, to get
475 = 1 x 475 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 475 is 1
Notice that 1 = HCF(475,1) .
