HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 618, 788 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 618, 788 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 618, 788 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 618, 788 is 2.
HCF(618, 788) = 2
HCF of 618, 788 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 618, 788 is 2.
Highest Common Factor of 618,788 is 2
Step 1: Since 788 > 618, we apply the division lemma to 788 and 618, to get
788 = 618 x 1 + 170
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 170 and 618, to get
618 = 170 x 3 + 108
Step 3: We consider the new divisor 170 and the new remainder 108, and apply the division lemma to get
170 = 108 x 1 + 62
We consider the new divisor 108 and the new remainder 62,and apply the division lemma to get
108 = 62 x 1 + 46
We consider the new divisor 62 and the new remainder 46,and apply the division lemma to get
62 = 46 x 1 + 16
We consider the new divisor 46 and the new remainder 16,and apply the division lemma to get
46 = 16 x 2 + 14
We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get
16 = 14 x 1 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 618 and 788 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(46,16) = HCF(62,46) = HCF(108,62) = HCF(170,108) = HCF(618,170) = HCF(788,618) .
