HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 697, 786, 170 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 697, 786, 170 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 784, 697, 786, 170 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 784, 697, 786, 170 is 1.
HCF(784, 697, 786, 170) = 1
HCF of 784, 697, 786, 170 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 784, 697, 786, 170 is 1.
Highest Common Factor of 784,697,786,170 is 1
Step 1: Since 784 > 697, we apply the division lemma to 784 and 697, to get
784 = 697 x 1 + 87
Step 2: Since the reminder 697 ≠ 0, we apply division lemma to 87 and 697, to get
697 = 87 x 8 + 1
Step 3: We consider the new divisor 87 and the new remainder 1, and apply the division lemma to get
87 = 1 x 87 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 784 and 697 is 1
Notice that 1 = HCF(87,1) = HCF(697,87) = HCF(784,697) .
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) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 170 > 1, we apply the division lemma to 170 and 1, to get
170 = 1 x 170 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 170 is 1
Notice that 1 = HCF(170,1) .
