HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 12840 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 454, 12840 is 2 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 454, 12840 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 454, 12840 is 2.
HCF(454, 12840) = 2
HCF of 454, 12840 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 454, 12840 is 2.
Highest Common Factor of 454,12840 is 2
Step 1: Since 12840 > 454, we apply the division lemma to 12840 and 454, to get
12840 = 454 x 28 + 128
Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 128 and 454, to get
454 = 128 x 3 + 70
Step 3: We consider the new divisor 128 and the new remainder 70, and apply the division lemma to get
128 = 70 x 1 + 58
We consider the new divisor 70 and the new remainder 58,and apply the division lemma to get
70 = 58 x 1 + 12
We consider the new divisor 58 and the new remainder 12,and apply the division lemma to get
58 = 12 x 4 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 454 and 12840 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(58,12) = HCF(70,58) = HCF(128,70) = HCF(454,128) = HCF(12840,454) .
