HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 840, 278 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 270, 840, 278 is 2 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, 840, 278 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, 840, 278 is 2.
HCF(270, 840, 278) = 2
HCF of 270, 840, 278 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, 840, 278 is 2.
Highest Common Factor of 270,840,278 is 2
Step 1: Since 840 > 270, we apply the division lemma to 840 and 270, to get
840 = 270 x 3 + 30
Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 30 and 270, to get
270 = 30 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 270 and 840 is 30
Notice that 30 = HCF(270,30) = HCF(840,270) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 278 > 30, we apply the division lemma to 278 and 30, to get
278 = 30 x 9 + 8
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 8 and 30, to get
30 = 8 x 3 + 6
Step 3: We consider the new divisor 8 and the new remainder 6, and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 30 and 278 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(30,8) = HCF(278,30) .
