HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 930, 590, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 930, 590, 989 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 930, 590, 989 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 930, 590, 989 is 1.
HCF(930, 590, 989) = 1
HCF of 930, 590, 989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 930, 590, 989 is 1.
Highest Common Factor of 930,590,989 is 1
Step 1: Since 930 > 590, we apply the division lemma to 930 and 590, to get
930 = 590 x 1 + 340
Step 2: Since the reminder 590 ≠ 0, we apply division lemma to 340 and 590, to get
590 = 340 x 1 + 250
Step 3: We consider the new divisor 340 and the new remainder 250, and apply the division lemma to get
340 = 250 x 1 + 90
We consider the new divisor 250 and the new remainder 90,and apply the division lemma to get
250 = 90 x 2 + 70
We consider the new divisor 90 and the new remainder 70,and apply the division lemma to get
90 = 70 x 1 + 20
We consider the new divisor 70 and the new remainder 20,and apply the division lemma to get
70 = 20 x 3 + 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 930 and 590 is 10
Notice that 10 = HCF(20,10) = HCF(70,20) = HCF(90,70) = HCF(250,90) = HCF(340,250) = HCF(590,340) = HCF(930,590) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 989 > 10, we apply the division lemma to 989 and 10, to get
989 = 10 x 98 + 9
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 9 and 10, to get
10 = 9 x 1 + 1
Step 3: We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 989 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(989,10) .
