HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 828, 330, 149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 828, 330, 149 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 828, 330, 149 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 828, 330, 149 is 1.
HCF(828, 330, 149) = 1
HCF of 828, 330, 149 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 828, 330, 149 is 1.
Highest Common Factor of 828,330,149 is 1
Step 1: Since 828 > 330, we apply the division lemma to 828 and 330, to get
828 = 330 x 2 + 168
Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 168 and 330, to get
330 = 168 x 1 + 162
Step 3: We consider the new divisor 168 and the new remainder 162, and apply the division lemma to get
168 = 162 x 1 + 6
We consider the new divisor 162 and the new remainder 6, and apply the division lemma to get
162 = 6 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 828 and 330 is 6
Notice that 6 = HCF(162,6) = HCF(168,162) = HCF(330,168) = HCF(828,330) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 149 > 6, we apply the division lemma to 149 and 6, to get
149 = 6 x 24 + 5
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get
6 = 5 x 1 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 149 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(149,6) .
