HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 7426, 5603 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 777, 7426, 5603 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 777, 7426, 5603 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 777, 7426, 5603 is 1.
HCF(777, 7426, 5603) = 1
HCF of 777, 7426, 5603 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 777, 7426, 5603 is 1.
Highest Common Factor of 777,7426,5603 is 1
Step 1: Since 7426 > 777, we apply the division lemma to 7426 and 777, to get
7426 = 777 x 9 + 433
Step 2: Since the reminder 777 ≠ 0, we apply division lemma to 433 and 777, to get
777 = 433 x 1 + 344
Step 3: We consider the new divisor 433 and the new remainder 344, and apply the division lemma to get
433 = 344 x 1 + 89
We consider the new divisor 344 and the new remainder 89,and apply the division lemma to get
344 = 89 x 3 + 77
We consider the new divisor 89 and the new remainder 77,and apply the division lemma to get
89 = 77 x 1 + 12
We consider the new divisor 77 and the new remainder 12,and apply the division lemma to get
77 = 12 x 6 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 777 and 7426 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(77,12) = HCF(89,77) = HCF(344,89) = HCF(433,344) = HCF(777,433) = HCF(7426,777) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 5603 > 1, we apply the division lemma to 5603 and 1, to get
5603 = 1 x 5603 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 5603 is 1
Notice that 1 = HCF(5603,1) .
