HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 936, 915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 730, 936, 915 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 730, 936, 915 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 730, 936, 915 is 1.
HCF(730, 936, 915) = 1
HCF of 730, 936, 915 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 730, 936, 915 is 1.
Highest Common Factor of 730,936,915 is 1
Step 1: Since 936 > 730, we apply the division lemma to 936 and 730, to get
936 = 730 x 1 + 206
Step 2: Since the reminder 730 ≠ 0, we apply division lemma to 206 and 730, to get
730 = 206 x 3 + 112
Step 3: We consider the new divisor 206 and the new remainder 112, and apply the division lemma to get
206 = 112 x 1 + 94
We consider the new divisor 112 and the new remainder 94,and apply the division lemma to get
112 = 94 x 1 + 18
We consider the new divisor 94 and the new remainder 18,and apply the division lemma to get
94 = 18 x 5 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 730 and 936 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(94,18) = HCF(112,94) = HCF(206,112) = HCF(730,206) = HCF(936,730) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 915 > 2, we apply the division lemma to 915 and 2, to get
915 = 2 x 457 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 915 is 1
Notice that 1 = HCF(2,1) = HCF(915,2) .
