HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 492, 409 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 270, 492, 409 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 270, 492, 409 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 270, 492, 409 is 1.
HCF(270, 492, 409) = 1
HCF of 270, 492, 409 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 270, 492, 409 is 1.
Highest Common Factor of 270,492,409 is 1
Step 1: Since 492 > 270, we apply the division lemma to 492 and 270, to get
492 = 270 x 1 + 222
Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 222 and 270, to get
270 = 222 x 1 + 48
Step 3: We consider the new divisor 222 and the new remainder 48, and apply the division lemma to get
222 = 48 x 4 + 30
We consider the new divisor 48 and the new remainder 30,and apply the division lemma to get
48 = 30 x 1 + 18
We consider the new divisor 30 and the new remainder 18,and apply the division lemma to get
30 = 18 x 1 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 270 and 492 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(48,30) = HCF(222,48) = HCF(270,222) = HCF(492,270) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 409 > 6, we apply the division lemma to 409 and 6, to get
409 = 6 x 68 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 409 is 1
Notice that 1 = HCF(6,1) = HCF(409,6) .
