HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 775, 930, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 775, 930, 471 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 775, 930, 471 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 775, 930, 471 is 1.
HCF(775, 930, 471) = 1
HCF of 775, 930, 471 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 775, 930, 471 is 1.
Highest Common Factor of 775,930,471 is 1
Step 1: Since 930 > 775, we apply the division lemma to 930 and 775, to get
930 = 775 x 1 + 155
Step 2: Since the reminder 775 ≠ 0, we apply division lemma to 155 and 775, to get
775 = 155 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 155, the HCF of 775 and 930 is 155
Notice that 155 = HCF(775,155) = HCF(930,775) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 471 > 155, we apply the division lemma to 471 and 155, to get
471 = 155 x 3 + 6
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 6 and 155, to get
155 = 6 x 25 + 5
Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 155 and 471 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(155,6) = HCF(471,155) .
