HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 957, 310 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 957, 310 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 870, 957, 310 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, 957, 310 is 1.
HCF(870, 957, 310) = 1
HCF of 870, 957, 310 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, 957, 310 is 1.
Highest Common Factor of 870,957,310 is 1
Step 1: Since 957 > 870, we apply the division lemma to 957 and 870, to get
957 = 870 x 1 + 87
Step 2: Since the reminder 870 ≠ 0, we apply division lemma to 87 and 870, to get
870 = 87 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 87, the HCF of 870 and 957 is 87
Notice that 87 = HCF(870,87) = HCF(957,870) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 310 > 87, we apply the division lemma to 310 and 87, to get
310 = 87 x 3 + 49
Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 49 and 87, to get
87 = 49 x 1 + 38
Step 3: We consider the new divisor 49 and the new remainder 38, and apply the division lemma to get
49 = 38 x 1 + 11
We consider the new divisor 38 and the new remainder 11,and apply the division lemma to get
38 = 11 x 3 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 87 and 310 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(38,11) = HCF(49,38) = HCF(87,49) = HCF(310,87) .
