HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 650, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 650, 71 is 1 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 720, 650, 71 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 720, 650, 71 is 1.
HCF(720, 650, 71) = 1
HCF of 720, 650, 71 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 650, 71 is 1.
Highest Common Factor of 720,650,71 is 1
Step 1: Since 720 > 650, we apply the division lemma to 720 and 650, to get
720 = 650 x 1 + 70
Step 2: Since the reminder 650 ≠ 0, we apply division lemma to 70 and 650, to get
650 = 70 x 9 + 20
Step 3: We consider the new divisor 70 and the new remainder 20, and apply the division lemma to get
70 = 20 x 3 + 10
We consider the new divisor 20 and the new remainder 10, and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 720 and 650 is 10
Notice that 10 = HCF(20,10) = HCF(70,20) = HCF(650,70) = HCF(720,650) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 71 > 10, we apply the division lemma to 71 and 10, to get
71 = 10 x 7 + 1
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 1 and 10, to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 71 is 1
Notice that 1 = HCF(10,1) = HCF(71,10) .
