HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 78, 94, 844, 484 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 78, 94, 844, 484 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 78, 94, 844, 484 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 78, 94, 844, 484 is 2.
HCF(78, 94, 844, 484) = 2
HCF of 78, 94, 844, 484 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 78, 94, 844, 484 is 2.
Highest Common Factor of 78,94,844,484 is 2
Step 1: Since 94 > 78, we apply the division lemma to 94 and 78, to get
94 = 78 x 1 + 16
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 16 and 78, to get
78 = 16 x 4 + 14
Step 3: We consider the new divisor 16 and the new remainder 14, and apply the division lemma to get
16 = 14 x 1 + 2
We consider the new divisor 14 and the new remainder 2, and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 78 and 94 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(78,16) = HCF(94,78) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 844 > 2, we apply the division lemma to 844 and 2, to get
844 = 2 x 422 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 844 is 2
Notice that 2 = HCF(844,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 484 > 2, we apply the division lemma to 484 and 2, to get
484 = 2 x 242 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 484 is 2
Notice that 2 = HCF(484,2) .
