HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 712, 982, 970 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 712, 982, 970 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 712, 982, 970 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 712, 982, 970 is 2.
HCF(712, 982, 970) = 2
HCF of 712, 982, 970 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 712, 982, 970 is 2.
Highest Common Factor of 712,982,970 is 2
Step 1: Since 982 > 712, we apply the division lemma to 982 and 712, to get
982 = 712 x 1 + 270
Step 2: Since the reminder 712 ≠ 0, we apply division lemma to 270 and 712, to get
712 = 270 x 2 + 172
Step 3: We consider the new divisor 270 and the new remainder 172, and apply the division lemma to get
270 = 172 x 1 + 98
We consider the new divisor 172 and the new remainder 98,and apply the division lemma to get
172 = 98 x 1 + 74
We consider the new divisor 98 and the new remainder 74,and apply the division lemma to get
98 = 74 x 1 + 24
We consider the new divisor 74 and the new remainder 24,and apply the division lemma to get
74 = 24 x 3 + 2
We consider the new divisor 24 and the new remainder 2,and apply the division lemma to get
24 = 2 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 712 and 982 is 2
Notice that 2 = HCF(24,2) = HCF(74,24) = HCF(98,74) = HCF(172,98) = HCF(270,172) = HCF(712,270) = HCF(982,712) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 970 > 2, we apply the division lemma to 970 and 2, to get
970 = 2 x 485 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 970 is 2
Notice that 2 = HCF(970,2) .
