HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 828 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 828 is 18 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 342, 828 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 342, 828 is 18.
HCF(342, 828) = 18
HCF of 342, 828 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 828 is 18.
Highest Common Factor of 342,828 is 18
Step 1: Since 828 > 342, we apply the division lemma to 828 and 342, to get
828 = 342 x 2 + 144
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 144 and 342, to get
342 = 144 x 2 + 54
Step 3: We consider the new divisor 144 and the new remainder 54, and apply the division lemma to get
144 = 54 x 2 + 36
We consider the new divisor 54 and the new remainder 36,and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18,and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 342 and 828 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(144,54) = HCF(342,144) = HCF(828,342) .
