HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 320, 216, 930 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 320, 216, 930 is 2 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 870, 320, 216, 930 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 870, 320, 216, 930 is 2.
HCF(870, 320, 216, 930) = 2
HCF of 870, 320, 216, 930 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 320, 216, 930 is 2.
Highest Common Factor of 870,320,216,930 is 2
Step 1: Since 870 > 320, we apply the division lemma to 870 and 320, to get
870 = 320 x 2 + 230
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 230 and 320, to get
320 = 230 x 1 + 90
Step 3: We consider the new divisor 230 and the new remainder 90, and apply the division lemma to get
230 = 90 x 2 + 50
We consider the new divisor 90 and the new remainder 50,and apply the division lemma to get
90 = 50 x 1 + 40
We consider the new divisor 50 and the new remainder 40,and apply the division lemma to get
50 = 40 x 1 + 10
We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 870 and 320 is 10
Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(90,50) = HCF(230,90) = HCF(320,230) = HCF(870,320) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 216 > 10, we apply the division lemma to 216 and 10, to get
216 = 10 x 21 + 6
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get
10 = 6 x 1 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 216 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(216,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 930 > 2, we apply the division lemma to 930 and 2, to get
930 = 2 x 465 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 930 is 2
Notice that 2 = HCF(930,2) .
