HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 78, 56, 92, 830 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 78, 56, 92, 830 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, 56, 92, 830 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, 56, 92, 830 is 2.
HCF(78, 56, 92, 830) = 2
HCF of 78, 56, 92, 830 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, 56, 92, 830 is 2.
Highest Common Factor of 78,56,92,830 is 2
Step 1: Since 78 > 56, we apply the division lemma to 78 and 56, to get
78 = 56 x 1 + 22
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 22 and 56, to get
56 = 22 x 2 + 12
Step 3: We consider the new divisor 22 and the new remainder 12, and apply the division lemma to get
22 = 12 x 1 + 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 78 and 56 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(56,22) = HCF(78,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 92 > 2, we apply the division lemma to 92 and 2, to get
92 = 2 x 46 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 92 is 2
Notice that 2 = HCF(92,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 830 > 2, we apply the division lemma to 830 and 2, to get
830 = 2 x 415 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 830 is 2
Notice that 2 = HCF(830,2) .
