HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 678, 697, 282 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 678, 697, 282 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 678, 697, 282 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 678, 697, 282 is 1.
HCF(678, 697, 282) = 1
HCF of 678, 697, 282 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 678, 697, 282 is 1.
Highest Common Factor of 678,697,282 is 1
Step 1: Since 697 > 678, we apply the division lemma to 697 and 678, to get
697 = 678 x 1 + 19
Step 2: Since the reminder 678 ≠ 0, we apply division lemma to 19 and 678, to get
678 = 19 x 35 + 13
Step 3: We consider the new divisor 19 and the new remainder 13, and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 678 and 697 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(678,19) = HCF(697,678) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 282 > 1, we apply the division lemma to 282 and 1, to get
282 = 1 x 282 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 282 is 1
Notice that 1 = HCF(282,1) .
