HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 479, 78, 312 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 479, 78, 312 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 975, 479, 78, 312 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 975, 479, 78, 312 is 1.
HCF(975, 479, 78, 312) = 1
HCF of 975, 479, 78, 312 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 479, 78, 312 is 1.
Highest Common Factor of 975,479,78,312 is 1
Step 1: Since 975 > 479, we apply the division lemma to 975 and 479, to get
975 = 479 x 2 + 17
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 17 and 479, to get
479 = 17 x 28 + 3
Step 3: We consider the new divisor 17 and the new remainder 3, and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 975 and 479 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(479,17) = HCF(975,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 312 > 1, we apply the division lemma to 312 and 1, to get
312 = 1 x 312 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 312 is 1
Notice that 1 = HCF(312,1) .
