HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 786, 519 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 786, 519 is 3 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 918, 786, 519 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 918, 786, 519 is 3.
HCF(918, 786, 519) = 3
HCF of 918, 786, 519 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 786, 519 is 3.
Highest Common Factor of 918,786,519 is 3
Step 1: Since 918 > 786, we apply the division lemma to 918 and 786, to get
918 = 786 x 1 + 132
Step 2: Since the reminder 786 ≠ 0, we apply division lemma to 132 and 786, to get
786 = 132 x 5 + 126
Step 3: We consider the new divisor 132 and the new remainder 126, and apply the division lemma to get
132 = 126 x 1 + 6
We consider the new divisor 126 and the new remainder 6, and apply the division lemma to get
126 = 6 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 918 and 786 is 6
Notice that 6 = HCF(126,6) = HCF(132,126) = HCF(786,132) = HCF(918,786) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 519 > 6, we apply the division lemma to 519 and 6, to get
519 = 6 x 86 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 519 is 3
Notice that 3 = HCF(6,3) = HCF(519,6) .
