HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 207, 139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 783, 207, 139 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 783, 207, 139 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 783, 207, 139 is 1.
HCF(783, 207, 139) = 1
HCF of 783, 207, 139 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 783, 207, 139 is 1.
Highest Common Factor of 783,207,139 is 1
Step 1: Since 783 > 207, we apply the division lemma to 783 and 207, to get
783 = 207 x 3 + 162
Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 162 and 207, to get
207 = 162 x 1 + 45
Step 3: We consider the new divisor 162 and the new remainder 45, and apply the division lemma to get
162 = 45 x 3 + 27
We consider the new divisor 45 and the new remainder 27,and apply the division lemma to get
45 = 27 x 1 + 18
We consider the new divisor 27 and the new remainder 18,and apply the division lemma to get
27 = 18 x 1 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 783 and 207 is 9
Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(45,27) = HCF(162,45) = HCF(207,162) = HCF(783,207) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 139 > 9, we apply the division lemma to 139 and 9, to get
139 = 9 x 15 + 4
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 4 and 9, to get
9 = 4 x 2 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 139 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(139,9) .
