HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 215, 778, 614 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 215, 778, 614 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 215, 778, 614 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 215, 778, 614 is 1.
HCF(215, 778, 614) = 1
HCF of 215, 778, 614 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 215, 778, 614 is 1.
Highest Common Factor of 215,778,614 is 1
Step 1: Since 778 > 215, we apply the division lemma to 778 and 215, to get
778 = 215 x 3 + 133
Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 133 and 215, to get
215 = 133 x 1 + 82
Step 3: We consider the new divisor 133 and the new remainder 82, and apply the division lemma to get
133 = 82 x 1 + 51
We consider the new divisor 82 and the new remainder 51,and apply the division lemma to get
82 = 51 x 1 + 31
We consider the new divisor 51 and the new remainder 31,and apply the division lemma to get
51 = 31 x 1 + 20
We consider the new divisor 31 and the new remainder 20,and apply the division lemma to get
31 = 20 x 1 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 215 and 778 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(31,20) = HCF(51,31) = HCF(82,51) = HCF(133,82) = HCF(215,133) = HCF(778,215) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 614 > 1, we apply the division lemma to 614 and 1, to get
614 = 1 x 614 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 614 is 1
Notice that 1 = HCF(614,1) .
