HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 488, 870 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 488, 870 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 488, 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 488, 870 is 2.
HCF(488, 870) = 2
HCF of 488, 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 488, 870 is 2.
Highest Common Factor of 488,870 is 2
Step 1: Since 870 > 488, we apply the division lemma to 870 and 488, to get
870 = 488 x 1 + 382
Step 2: Since the reminder 488 ≠ 0, we apply division lemma to 382 and 488, to get
488 = 382 x 1 + 106
Step 3: We consider the new divisor 382 and the new remainder 106, and apply the division lemma to get
382 = 106 x 3 + 64
We consider the new divisor 106 and the new remainder 64,and apply the division lemma to get
106 = 64 x 1 + 42
We consider the new divisor 64 and the new remainder 42,and apply the division lemma to get
64 = 42 x 1 + 22
We consider the new divisor 42 and the new remainder 22,and apply the division lemma to get
42 = 22 x 1 + 20
We consider the new divisor 22 and the new remainder 20,and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 488 and 870 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(42,22) = HCF(64,42) = HCF(106,64) = HCF(382,106) = HCF(488,382) = HCF(870,488) .
