HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 884, 715 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 728, 884, 715 is 13 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 728, 884, 715 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 728, 884, 715 is 13.
HCF(728, 884, 715) = 13
HCF of 728, 884, 715 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 728, 884, 715 is 13.
Highest Common Factor of 728,884,715 is 13
Step 1: Since 884 > 728, we apply the division lemma to 884 and 728, to get
884 = 728 x 1 + 156
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 156 and 728, to get
728 = 156 x 4 + 104
Step 3: We consider the new divisor 156 and the new remainder 104, and apply the division lemma to get
156 = 104 x 1 + 52
We consider the new divisor 104 and the new remainder 52, and apply the division lemma to get
104 = 52 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 52, the HCF of 728 and 884 is 52
Notice that 52 = HCF(104,52) = HCF(156,104) = HCF(728,156) = HCF(884,728) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 715 > 52, we apply the division lemma to 715 and 52, to get
715 = 52 x 13 + 39
Step 2: Since the reminder 52 ≠ 0, we apply division lemma to 39 and 52, to get
52 = 39 x 1 + 13
Step 3: We consider the new divisor 39 and the new remainder 13, and apply the division lemma to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 52 and 715 is 13
Notice that 13 = HCF(39,13) = HCF(52,39) = HCF(715,52) .
