HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 894, 978, 942 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 894, 978, 942 is 6 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 894, 978, 942 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 894, 978, 942 is 6.
HCF(894, 978, 942) = 6
HCF of 894, 978, 942 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 894, 978, 942 is 6.
Highest Common Factor of 894,978,942 is 6
Step 1: Since 978 > 894, we apply the division lemma to 978 and 894, to get
978 = 894 x 1 + 84
Step 2: Since the reminder 894 ≠ 0, we apply division lemma to 84 and 894, to get
894 = 84 x 10 + 54
Step 3: We consider the new divisor 84 and the new remainder 54, and apply the division lemma to get
84 = 54 x 1 + 30
We consider the new divisor 54 and the new remainder 30,and apply the division lemma to get
54 = 30 x 1 + 24
We consider the new divisor 30 and the new remainder 24,and apply the division lemma to get
30 = 24 x 1 + 6
We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get
24 = 6 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 894 and 978 is 6
Notice that 6 = HCF(24,6) = HCF(30,24) = HCF(54,30) = HCF(84,54) = HCF(894,84) = HCF(978,894) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 942 > 6, we apply the division lemma to 942 and 6, to get
942 = 6 x 157 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 942 is 6
Notice that 6 = HCF(942,6) .
