HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1422, 8478 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 1422, 8478 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 1422, 8478 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 1422, 8478 is 18.
HCF(1422, 8478) = 18
HCF of 1422, 8478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1422, 8478 is 18.
Highest Common Factor of 1422,8478 is 18
Step 1: Since 8478 > 1422, we apply the division lemma to 8478 and 1422, to get
8478 = 1422 x 5 + 1368
Step 2: Since the reminder 1422 ≠ 0, we apply division lemma to 1368 and 1422, to get
1422 = 1368 x 1 + 54
Step 3: We consider the new divisor 1368 and the new remainder 54, and apply the division lemma to get
1368 = 54 x 25 + 18
We consider the new divisor 54 and the new remainder 18, and apply the division lemma to get
54 = 18 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 1422 and 8478 is 18
Notice that 18 = HCF(54,18) = HCF(1368,54) = HCF(1422,1368) = HCF(8478,1422) .
