HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 280 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 786, 280 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 786, 280 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 786, 280 is 2.
HCF(786, 280) = 2
HCF of 786, 280 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 786, 280 is 2.
Highest Common Factor of 786,280 is 2
Step 1: Since 786 > 280, we apply the division lemma to 786 and 280, to get
786 = 280 x 2 + 226
Step 2: Since the reminder 280 ≠ 0, we apply division lemma to 226 and 280, to get
280 = 226 x 1 + 54
Step 3: We consider the new divisor 226 and the new remainder 54, and apply the division lemma to get
226 = 54 x 4 + 10
We consider the new divisor 54 and the new remainder 10,and apply the division lemma to get
54 = 10 x 5 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 786 and 280 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(54,10) = HCF(226,54) = HCF(280,226) = HCF(786,280) .
