HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 130, 720 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 130, 720 is 10 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 130, 720 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 130, 720 is 10.
HCF(130, 720) = 10
HCF of 130, 720 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 130, 720 is 10.
Highest Common Factor of 130,720 is 10
Step 1: Since 720 > 130, we apply the division lemma to 720 and 130, to get
720 = 130 x 5 + 70
Step 2: Since the reminder 130 ≠ 0, we apply division lemma to 70 and 130, to get
130 = 70 x 1 + 60
Step 3: We consider the new divisor 70 and the new remainder 60, and apply the division lemma to get
70 = 60 x 1 + 10
We consider the new divisor 60 and the new remainder 10, and apply the division lemma to get
60 = 10 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 130 and 720 is 10
Notice that 10 = HCF(60,10) = HCF(70,60) = HCF(130,70) = HCF(720,130) .
