HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 153, 873, 870 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 153, 873, 870 is 3 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 153, 873, 870 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 153, 873, 870 is 3.
HCF(153, 873, 870) = 3
HCF of 153, 873, 870 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 153, 873, 870 is 3.
Highest Common Factor of 153,873,870 is 3
Step 1: Since 873 > 153, we apply the division lemma to 873 and 153, to get
873 = 153 x 5 + 108
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 108 and 153, to get
153 = 108 x 1 + 45
Step 3: We consider the new divisor 108 and the new remainder 45, and apply the division lemma to get
108 = 45 x 2 + 18
We consider the new divisor 45 and the new remainder 18,and apply the division lemma to get
45 = 18 x 2 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 153 and 873 is 9
Notice that 9 = HCF(18,9) = HCF(45,18) = HCF(108,45) = HCF(153,108) = HCF(873,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 870 > 9, we apply the division lemma to 870 and 9, to get
870 = 9 x 96 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 870 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(870,9) .
