HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 828, 1218 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 828, 1218 is 6 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, 1218 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, 1218 is 6.
HCF(828, 1218) = 6
HCF of 828, 1218 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, 1218 is 6.
Highest Common Factor of 828,1218 is 6
Step 1: Since 1218 > 828, we apply the division lemma to 1218 and 828, to get
1218 = 828 x 1 + 390
Step 2: Since the reminder 828 ≠ 0, we apply division lemma to 390 and 828, to get
828 = 390 x 2 + 48
Step 3: We consider the new divisor 390 and the new remainder 48, and apply the division lemma to get
390 = 48 x 8 + 6
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 828 and 1218 is 6
Notice that 6 = HCF(48,6) = HCF(390,48) = HCF(828,390) = HCF(1218,828) .
