HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 140, 540 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 140, 540 is 10 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 790, 140, 540 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 790, 140, 540 is 10.
HCF(790, 140, 540) = 10
HCF of 790, 140, 540 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 140, 540 is 10.
Highest Common Factor of 790,140,540 is 10
Step 1: Since 790 > 140, we apply the division lemma to 790 and 140, to get
790 = 140 x 5 + 90
Step 2: Since the reminder 140 ≠ 0, we apply division lemma to 90 and 140, to get
140 = 90 x 1 + 50
Step 3: We consider the new divisor 90 and the new remainder 50, and apply the division lemma to get
90 = 50 x 1 + 40
We consider the new divisor 50 and the new remainder 40,and apply the division lemma to get
50 = 40 x 1 + 10
We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 790 and 140 is 10
Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(90,50) = HCF(140,90) = HCF(790,140) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 540 > 10, we apply the division lemma to 540 and 10, to get
540 = 10 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 10 and 540 is 10
Notice that 10 = HCF(540,10) .
