HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 570, 930, 261 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 570, 930, 261 is 3 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 570, 930, 261 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 570, 930, 261 is 3.
HCF(570, 930, 261) = 3
HCF of 570, 930, 261 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 570, 930, 261 is 3.
Highest Common Factor of 570,930,261 is 3
Step 1: Since 930 > 570, we apply the division lemma to 930 and 570, to get
930 = 570 x 1 + 360
Step 2: Since the reminder 570 ≠ 0, we apply division lemma to 360 and 570, to get
570 = 360 x 1 + 210
Step 3: We consider the new divisor 360 and the new remainder 210, and apply the division lemma to get
360 = 210 x 1 + 150
We consider the new divisor 210 and the new remainder 150,and apply the division lemma to get
210 = 150 x 1 + 60
We consider the new divisor 150 and the new remainder 60,and apply the division lemma to get
150 = 60 x 2 + 30
We consider the new divisor 60 and the new remainder 30,and apply the division lemma to get
60 = 30 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 570 and 930 is 30
Notice that 30 = HCF(60,30) = HCF(150,60) = HCF(210,150) = HCF(360,210) = HCF(570,360) = HCF(930,570) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 261 > 30, we apply the division lemma to 261 and 30, to get
261 = 30 x 8 + 21
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 21 and 30, to get
30 = 21 x 1 + 9
Step 3: We consider the new divisor 21 and the new remainder 9, and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 30 and 261 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(30,21) = HCF(261,30) .
