HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 418, 714, 778 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 418, 714, 778 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 418, 714, 778 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 418, 714, 778 is 2.
HCF(418, 714, 778) = 2
HCF of 418, 714, 778 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 418, 714, 778 is 2.
Highest Common Factor of 418,714,778 is 2
Step 1: Since 714 > 418, we apply the division lemma to 714 and 418, to get
714 = 418 x 1 + 296
Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 296 and 418, to get
418 = 296 x 1 + 122
Step 3: We consider the new divisor 296 and the new remainder 122, and apply the division lemma to get
296 = 122 x 2 + 52
We consider the new divisor 122 and the new remainder 52,and apply the division lemma to get
122 = 52 x 2 + 18
We consider the new divisor 52 and the new remainder 18,and apply the division lemma to get
52 = 18 x 2 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 418 and 714 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(52,18) = HCF(122,52) = HCF(296,122) = HCF(418,296) = HCF(714,418) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 778 > 2, we apply the division lemma to 778 and 2, to get
778 = 2 x 389 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 778 is 2
Notice that 2 = HCF(778,2) .
