HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 754, 915, 720 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 754, 915, 720 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 754, 915, 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 754, 915, 720 is 1.
HCF(754, 915, 720) = 1
HCF of 754, 915, 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 754, 915, 720 is 1.
Highest Common Factor of 754,915,720 is 1
Step 1: Since 915 > 754, we apply the division lemma to 915 and 754, to get
915 = 754 x 1 + 161
Step 2: Since the reminder 754 ≠ 0, we apply division lemma to 161 and 754, to get
754 = 161 x 4 + 110
Step 3: We consider the new divisor 161 and the new remainder 110, and apply the division lemma to get
161 = 110 x 1 + 51
We consider the new divisor 110 and the new remainder 51,and apply the division lemma to get
110 = 51 x 2 + 8
We consider the new divisor 51 and the new remainder 8,and apply the division lemma to get
51 = 8 x 6 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 754 and 915 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(51,8) = HCF(110,51) = HCF(161,110) = HCF(754,161) = HCF(915,754) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 1, we apply the division lemma to 720 and 1, to get
720 = 1 x 720 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1
Notice that 1 = HCF(720,1) .
