HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 289, 708, 999, 785 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 289, 708, 999, 785 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 289, 708, 999, 785 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 289, 708, 999, 785 is 1.
HCF(289, 708, 999, 785) = 1
HCF of 289, 708, 999, 785 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 289, 708, 999, 785 is 1.
Highest Common Factor of 289,708,999,785 is 1
Step 1: Since 708 > 289, we apply the division lemma to 708 and 289, to get
708 = 289 x 2 + 130
Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 130 and 289, to get
289 = 130 x 2 + 29
Step 3: We consider the new divisor 130 and the new remainder 29, and apply the division lemma to get
130 = 29 x 4 + 14
We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get
29 = 14 x 2 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 289 and 708 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(130,29) = HCF(289,130) = HCF(708,289) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 999 > 1, we apply the division lemma to 999 and 1, to get
999 = 1 x 999 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 999 is 1
Notice that 1 = HCF(999,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 785 > 1, we apply the division lemma to 785 and 1, to get
785 = 1 x 785 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 785 is 1
Notice that 1 = HCF(785,1) .
