HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 828, 515, 870, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 828, 515, 870, 985 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 828, 515, 870, 985 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 828, 515, 870, 985 is 1.
HCF(828, 515, 870, 985) = 1
HCF of 828, 515, 870, 985 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 828, 515, 870, 985 is 1.
Highest Common Factor of 828,515,870,985 is 1
Step 1: Since 828 > 515, we apply the division lemma to 828 and 515, to get
828 = 515 x 1 + 313
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 313 and 515, to get
515 = 313 x 1 + 202
Step 3: We consider the new divisor 313 and the new remainder 202, and apply the division lemma to get
313 = 202 x 1 + 111
We consider the new divisor 202 and the new remainder 111,and apply the division lemma to get
202 = 111 x 1 + 91
We consider the new divisor 111 and the new remainder 91,and apply the division lemma to get
111 = 91 x 1 + 20
We consider the new divisor 91 and the new remainder 20,and apply the division lemma to get
91 = 20 x 4 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 828 and 515 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(91,20) = HCF(111,91) = HCF(202,111) = HCF(313,202) = HCF(515,313) = HCF(828,515) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 870 > 1, we apply the division lemma to 870 and 1, to get
870 = 1 x 870 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 870 is 1
Notice that 1 = HCF(870,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 985 > 1, we apply the division lemma to 985 and 1, to get
985 = 1 x 985 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 985 is 1
Notice that 1 = HCF(985,1) .
