HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 40, 970, 618 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 40, 970, 618 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 40, 970, 618 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 40, 970, 618 is 2.
HCF(40, 970, 618) = 2
HCF of 40, 970, 618 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 40, 970, 618 is 2.
Highest Common Factor of 40,970,618 is 2
Step 1: Since 970 > 40, we apply the division lemma to 970 and 40, to get
970 = 40 x 24 + 10
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 10 and 40, to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 40 and 970 is 10
Notice that 10 = HCF(40,10) = HCF(970,40) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 618 > 10, we apply the division lemma to 618 and 10, to get
618 = 10 x 61 + 8
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 8 and 10, to get
10 = 8 x 1 + 2
Step 3: We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 618 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(618,10) .
