HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 873, 478, 787, 298 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 873, 478, 787, 298 is 1 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 873, 478, 787, 298 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 873, 478, 787, 298 is 1.
HCF(873, 478, 787, 298) = 1
HCF of 873, 478, 787, 298 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 873, 478, 787, 298 is 1.
Highest Common Factor of 873,478,787,298 is 1
Step 1: Since 873 > 478, we apply the division lemma to 873 and 478, to get
873 = 478 x 1 + 395
Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 395 and 478, to get
478 = 395 x 1 + 83
Step 3: We consider the new divisor 395 and the new remainder 83, and apply the division lemma to get
395 = 83 x 4 + 63
We consider the new divisor 83 and the new remainder 63,and apply the division lemma to get
83 = 63 x 1 + 20
We consider the new divisor 63 and the new remainder 20,and apply the division lemma to get
63 = 20 x 3 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 873 and 478 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(63,20) = HCF(83,63) = HCF(395,83) = HCF(478,395) = HCF(873,478) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 787 > 1, we apply the division lemma to 787 and 1, to get
787 = 1 x 787 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 787 is 1
Notice that 1 = HCF(787,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 298 > 1, we apply the division lemma to 298 and 1, to get
298 = 1 x 298 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 298 is 1
Notice that 1 = HCF(298,1) .
