HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 828, 141 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 828, 141 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 390, 828, 141 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 390, 828, 141 is 3.
HCF(390, 828, 141) = 3
HCF of 390, 828, 141 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 828, 141 is 3.
Highest Common Factor of 390,828,141 is 3
Step 1: Since 828 > 390, we apply the division lemma to 828 and 390, to get
828 = 390 x 2 + 48
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 48 and 390, to get
390 = 48 x 8 + 6
Step 3: We consider the new divisor 48 and the new remainder 6, and apply the division lemma to get
48 = 6 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 390 and 828 is 6
Notice that 6 = HCF(48,6) = HCF(390,48) = HCF(828,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 141 > 6, we apply the division lemma to 141 and 6, to get
141 = 6 x 23 + 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 141 is 3
Notice that 3 = HCF(6,3) = HCF(141,6) .
