HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 955, 130, 720 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 955, 130, 720 is 5 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 955, 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 955, 130, 720 is 5.
HCF(955, 130, 720) = 5
HCF of 955, 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 955, 130, 720 is 5.
Highest Common Factor of 955,130,720 is 5
Step 1: Since 955 > 130, we apply the division lemma to 955 and 130, to get
955 = 130 x 7 + 45
Step 2: Since the reminder 130 ≠ 0, we apply division lemma to 45 and 130, to get
130 = 45 x 2 + 40
Step 3: We consider the new divisor 45 and the new remainder 40, and apply the division lemma to get
45 = 40 x 1 + 5
We consider the new divisor 40 and the new remainder 5, and apply the division lemma to get
40 = 5 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 955 and 130 is 5
Notice that 5 = HCF(40,5) = HCF(45,40) = HCF(130,45) = HCF(955,130) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 5, we apply the division lemma to 720 and 5, to get
720 = 5 x 144 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 720 is 5
Notice that 5 = HCF(720,5) .
