HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 978 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 730, 978 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 730, 978 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 730, 978 is 2.
HCF(730, 978) = 2
HCF of 730, 978 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 730, 978 is 2.
Highest Common Factor of 730,978 is 2
Step 1: Since 978 > 730, we apply the division lemma to 978 and 730, to get
978 = 730 x 1 + 248
Step 2: Since the reminder 730 ≠ 0, we apply division lemma to 248 and 730, to get
730 = 248 x 2 + 234
Step 3: We consider the new divisor 248 and the new remainder 234, and apply the division lemma to get
248 = 234 x 1 + 14
We consider the new divisor 234 and the new remainder 14,and apply the division lemma to get
234 = 14 x 16 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 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 730 and 978 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(234,14) = HCF(248,234) = HCF(730,248) = HCF(978,730) .
