HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 870 i.e. 30 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 870 is 30 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 630, 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 630, 870 is 30.
HCF(630, 870) = 30
HCF of 630, 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 630, 870 is 30.
Highest Common Factor of 630,870 is 30
Step 1: Since 870 > 630, we apply the division lemma to 870 and 630, to get
870 = 630 x 1 + 240
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 240 and 630, to get
630 = 240 x 2 + 150
Step 3: We consider the new divisor 240 and the new remainder 150, and apply the division lemma to get
240 = 150 x 1 + 90
We consider the new divisor 150 and the new remainder 90,and apply the division lemma to get
150 = 90 x 1 + 60
We consider the new divisor 90 and the new remainder 60,and apply the division lemma to get
90 = 60 x 1 + 30
We consider the new divisor 60 and the new remainder 30,and apply the division lemma to get
60 = 30 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 630 and 870 is 30
Notice that 30 = HCF(60,30) = HCF(90,60) = HCF(150,90) = HCF(240,150) = HCF(630,240) = HCF(870,630) .
