HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 875, 356 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 875, 356 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, 875, 356 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, 875, 356 is 1.
HCF(784, 875, 356) = 1
HCF of 784, 875, 356 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, 875, 356 is 1.
Highest Common Factor of 784,875,356 is 1
Step 1: Since 875 > 784, we apply the division lemma to 875 and 784, to get
875 = 784 x 1 + 91
Step 2: Since the reminder 784 ≠ 0, we apply division lemma to 91 and 784, to get
784 = 91 x 8 + 56
Step 3: We consider the new divisor 91 and the new remainder 56, and apply the division lemma to get
91 = 56 x 1 + 35
We consider the new divisor 56 and the new remainder 35,and apply the division lemma to get
56 = 35 x 1 + 21
We consider the new divisor 35 and the new remainder 21,and apply the division lemma to get
35 = 21 x 1 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 784 and 875 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(56,35) = HCF(91,56) = HCF(784,91) = HCF(875,784) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 356 > 7, we apply the division lemma to 356 and 7, to get
356 = 7 x 50 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 356 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(356,7) .
