HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 742, 434 i.e. 14 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 742, 434 is 14 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, 742, 434 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, 742, 434 is 14.
HCF(980, 742, 434) = 14
HCF of 980, 742, 434 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, 742, 434 is 14.
Highest Common Factor of 980,742,434 is 14
Step 1: Since 980 > 742, we apply the division lemma to 980 and 742, to get
980 = 742 x 1 + 238
Step 2: Since the reminder 742 ≠ 0, we apply division lemma to 238 and 742, to get
742 = 238 x 3 + 28
Step 3: We consider the new divisor 238 and the new remainder 28, and apply the division lemma to get
238 = 28 x 8 + 14
We consider the new divisor 28 and the new remainder 14, and apply the division lemma to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 980 and 742 is 14
Notice that 14 = HCF(28,14) = HCF(238,28) = HCF(742,238) = HCF(980,742) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 434 > 14, we apply the division lemma to 434 and 14, to get
434 = 14 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 14 and 434 is 14
Notice that 14 = HCF(434,14) .
