HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 726, 390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 571, 726, 390 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, 726, 390 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, 726, 390 is 1.
HCF(571, 726, 390) = 1
HCF of 571, 726, 390 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, 726, 390 is 1.
Highest Common Factor of 571,726,390 is 1
Step 1: Since 726 > 571, we apply the division lemma to 726 and 571, to get
726 = 571 x 1 + 155
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 155 and 571, to get
571 = 155 x 3 + 106
Step 3: We consider the new divisor 155 and the new remainder 106, and apply the division lemma to get
155 = 106 x 1 + 49
We consider the new divisor 106 and the new remainder 49,and apply the division lemma to get
106 = 49 x 2 + 8
We consider the new divisor 49 and the new remainder 8,and apply the division lemma to get
49 = 8 x 6 + 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 571 and 726 is 1
Notice that 1 = HCF(8,1) = HCF(49,8) = HCF(106,49) = HCF(155,106) = HCF(571,155) = HCF(726,571) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get
390 = 1 x 390 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1
Notice that 1 = HCF(390,1) .
