HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 610, 680, 987 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 610, 680, 987 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 610, 680, 987 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 610, 680, 987 is 1.
HCF(610, 680, 987) = 1
HCF of 610, 680, 987 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 610, 680, 987 is 1.
Highest Common Factor of 610,680,987 is 1
Step 1: Since 680 > 610, we apply the division lemma to 680 and 610, to get
680 = 610 x 1 + 70
Step 2: Since the reminder 610 ≠ 0, we apply division lemma to 70 and 610, to get
610 = 70 x 8 + 50
Step 3: We consider the new divisor 70 and the new remainder 50, and apply the division lemma to get
70 = 50 x 1 + 20
We consider the new divisor 50 and the new remainder 20,and apply the division lemma to get
50 = 20 x 2 + 10
We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 610 and 680 is 10
Notice that 10 = HCF(20,10) = HCF(50,20) = HCF(70,50) = HCF(610,70) = HCF(680,610) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 987 > 10, we apply the division lemma to 987 and 10, to get
987 = 10 x 98 + 7
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 7 and 10, to get
10 = 7 x 1 + 3
Step 3: We consider the new divisor 7 and the new remainder 3, and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 987 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(987,10) .
