HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 978, 828, 255 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 978, 828, 255 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 978, 828, 255 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 978, 828, 255 is 3.
HCF(978, 828, 255) = 3
HCF of 978, 828, 255 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 978, 828, 255 is 3.
Highest Common Factor of 978,828,255 is 3
Step 1: Since 978 > 828, we apply the division lemma to 978 and 828, to get
978 = 828 x 1 + 150
Step 2: Since the reminder 828 ≠ 0, we apply division lemma to 150 and 828, to get
828 = 150 x 5 + 78
Step 3: We consider the new divisor 150 and the new remainder 78, and apply the division lemma to get
150 = 78 x 1 + 72
We consider the new divisor 78 and the new remainder 72,and apply the division lemma to get
78 = 72 x 1 + 6
We consider the new divisor 72 and the new remainder 6,and apply the division lemma to get
72 = 6 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 978 and 828 is 6
Notice that 6 = HCF(72,6) = HCF(78,72) = HCF(150,78) = HCF(828,150) = HCF(978,828) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 255 > 6, we apply the division lemma to 255 and 6, to get
255 = 6 x 42 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 255 is 3
Notice that 3 = HCF(6,3) = HCF(255,6) .
