HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 7077, 6742 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 7077, 6742 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 778, 7077, 6742 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 778, 7077, 6742 is 1.
HCF(778, 7077, 6742) = 1
HCF of 778, 7077, 6742 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 778, 7077, 6742 is 1.
Highest Common Factor of 778,7077,6742 is 1
Step 1: Since 7077 > 778, we apply the division lemma to 7077 and 778, to get
7077 = 778 x 9 + 75
Step 2: Since the reminder 778 ≠ 0, we apply division lemma to 75 and 778, to get
778 = 75 x 10 + 28
Step 3: We consider the new divisor 75 and the new remainder 28, and apply the division lemma to get
75 = 28 x 2 + 19
We consider the new divisor 28 and the new remainder 19,and apply the division lemma to get
28 = 19 x 1 + 9
We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get
19 = 9 x 2 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 778 and 7077 is 1
Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(28,19) = HCF(75,28) = HCF(778,75) = HCF(7077,778) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 6742 > 1, we apply the division lemma to 6742 and 1, to get
6742 = 1 x 6742 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 6742 is 1
Notice that 1 = HCF(6742,1) .
