HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 666, 6778, 7602 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 666, 6778, 7602 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 666, 6778, 7602 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 666, 6778, 7602 is 2.
HCF(666, 6778, 7602) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 666, 6778, 7602 is 2.
Step 1: Since 6778 > 666, we apply the division lemma to 6778 and 666, to get
6778 = 666 x 10 + 118
Step 2: Since the reminder 666 ≠ 0, we apply division lemma to 118 and 666, to get
666 = 118 x 5 + 76
Step 3: We consider the new divisor 118 and the new remainder 76, and apply the division lemma to get
118 = 76 x 1 + 42
We consider the new divisor 76 and the new remainder 42,and apply the division lemma to get
76 = 42 x 1 + 34
We consider the new divisor 42 and the new remainder 34,and apply the division lemma to get
42 = 34 x 1 + 8
We consider the new divisor 34 and the new remainder 8,and apply the division lemma to get
34 = 8 x 4 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 666 and 6778 is 2
Notice that 2 = HCF(8,2) = HCF(34,8) = HCF(42,34) = HCF(76,42) = HCF(118,76) = HCF(666,118) = HCF(6778,666) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7602 > 2, we apply the division lemma to 7602 and 2, to get
7602 = 2 x 3801 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 7602 is 2
Notice that 2 = HCF(7602,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
