HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 985, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 571, 985, 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 571, 985, 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 571, 985, 475 is 1.
HCF(571, 985, 475) = 1
HCF of 571, 985, 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 571, 985, 475 is 1.
Highest Common Factor of 571,985,475 is 1
Step 1: Since 985 > 571, we apply the division lemma to 985 and 571, to get
985 = 571 x 1 + 414
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 414 and 571, to get
571 = 414 x 1 + 157
Step 3: We consider the new divisor 414 and the new remainder 157, and apply the division lemma to get
414 = 157 x 2 + 100
We consider the new divisor 157 and the new remainder 100,and apply the division lemma to get
157 = 100 x 1 + 57
We consider the new divisor 100 and the new remainder 57,and apply the division lemma to get
100 = 57 x 1 + 43
We consider the new divisor 57 and the new remainder 43,and apply the division lemma to get
57 = 43 x 1 + 14
We consider the new divisor 43 and the new remainder 14,and apply the division lemma to get
43 = 14 x 3 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 571 and 985 is 1
Notice that 1 = HCF(14,1) = HCF(43,14) = HCF(57,43) = HCF(100,57) = HCF(157,100) = HCF(414,157) = HCF(571,414) = HCF(985,571) .
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) .
