HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 930, 209, 678 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 930, 209, 678 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 930, 209, 678 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 930, 209, 678 is 1.
HCF(930, 209, 678) = 1
HCF of 930, 209, 678 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 930, 209, 678 is 1.
Highest Common Factor of 930,209,678 is 1
Step 1: Since 930 > 209, we apply the division lemma to 930 and 209, to get
930 = 209 x 4 + 94
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 94 and 209, to get
209 = 94 x 2 + 21
Step 3: We consider the new divisor 94 and the new remainder 21, and apply the division lemma to get
94 = 21 x 4 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 930 and 209 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(94,21) = HCF(209,94) = HCF(930,209) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 678 > 1, we apply the division lemma to 678 and 1, to get
678 = 1 x 678 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 678 is 1
Notice that 1 = HCF(678,1) .
