HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 42, 762 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 42, 762 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 980, 42, 762 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 980, 42, 762 is 2.
HCF(980, 42, 762) = 2
HCF of 980, 42, 762 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 42, 762 is 2.
Highest Common Factor of 980,42,762 is 2
Step 1: Since 980 > 42, we apply the division lemma to 980 and 42, to get
980 = 42 x 23 + 14
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 14 and 42, to get
42 = 14 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 980 and 42 is 14
Notice that 14 = HCF(42,14) = HCF(980,42) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 14, we apply the division lemma to 762 and 14, to get
762 = 14 x 54 + 6
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 6 and 14, to get
14 = 6 x 2 + 2
Step 3: We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 14 and 762 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(762,14) .
