HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 907, 960, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 907, 960, 487 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 400, 907, 960, 487 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 400, 907, 960, 487 is 1.
HCF(400, 907, 960, 487) = 1
HCF of 400, 907, 960, 487 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 400, 907, 960, 487 is 1.
Highest Common Factor of 400,907,960,487 is 1
Step 1: Since 907 > 400, we apply the division lemma to 907 and 400, to get
907 = 400 x 2 + 107
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 107 and 400, to get
400 = 107 x 3 + 79
Step 3: We consider the new divisor 107 and the new remainder 79, and apply the division lemma to get
107 = 79 x 1 + 28
We consider the new divisor 79 and the new remainder 28,and apply the division lemma to get
79 = 28 x 2 + 23
We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get
28 = 23 x 1 + 5
We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get
23 = 5 x 4 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 400 and 907 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(79,28) = HCF(107,79) = HCF(400,107) = HCF(907,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 960 > 1, we apply the division lemma to 960 and 1, to get
960 = 1 x 960 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 960 is 1
Notice that 1 = HCF(960,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 487 > 1, we apply the division lemma to 487 and 1, to get
487 = 1 x 487 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 487 is 1
Notice that 1 = HCF(487,1) .
