HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 513, 786 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 513, 786 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 947, 513, 786 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 947, 513, 786 is 1.
HCF(947, 513, 786) = 1
HCF of 947, 513, 786 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 947, 513, 786 is 1.
Highest Common Factor of 947,513,786 is 1
Step 1: Since 947 > 513, we apply the division lemma to 947 and 513, to get
947 = 513 x 1 + 434
Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 434 and 513, to get
513 = 434 x 1 + 79
Step 3: We consider the new divisor 434 and the new remainder 79, and apply the division lemma to get
434 = 79 x 5 + 39
We consider the new divisor 79 and the new remainder 39,and apply the division lemma to get
79 = 39 x 2 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 513 is 1
Notice that 1 = HCF(39,1) = HCF(79,39) = HCF(434,79) = HCF(513,434) = HCF(947,513) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 786 > 1, we apply the division lemma to 786 and 1, to get
786 = 1 x 786 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 786 is 1
Notice that 1 = HCF(786,1) .
