HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 660, 758, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 287, 660, 758, 55 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 287, 660, 758, 55 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 287, 660, 758, 55 is 1.
HCF(287, 660, 758, 55) = 1
HCF of 287, 660, 758, 55 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 287, 660, 758, 55 is 1.
Highest Common Factor of 287,660,758,55 is 1
Step 1: Since 660 > 287, we apply the division lemma to 660 and 287, to get
660 = 287 x 2 + 86
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 86 and 287, to get
287 = 86 x 3 + 29
Step 3: We consider the new divisor 86 and the new remainder 29, and apply the division lemma to get
86 = 29 x 2 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 287 and 660 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(86,29) = HCF(287,86) = HCF(660,287) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 758 > 1, we apply the division lemma to 758 and 1, to get
758 = 1 x 758 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 758 is 1
Notice that 1 = HCF(758,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 1, we apply the division lemma to 55 and 1, to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 55 is 1
Notice that 1 = HCF(55,1) .
