HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 698, 758, 746, 99 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 698, 758, 746, 99 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 698, 758, 746, 99 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 698, 758, 746, 99 is 1.
HCF(698, 758, 746, 99) = 1
HCF of 698, 758, 746, 99 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 698, 758, 746, 99 is 1.
Highest Common Factor of 698,758,746,99 is 1
Step 1: Since 758 > 698, we apply the division lemma to 758 and 698, to get
758 = 698 x 1 + 60
Step 2: Since the reminder 698 ≠ 0, we apply division lemma to 60 and 698, to get
698 = 60 x 11 + 38
Step 3: We consider the new divisor 60 and the new remainder 38, and apply the division lemma to get
60 = 38 x 1 + 22
We consider the new divisor 38 and the new remainder 22,and apply the division lemma to get
38 = 22 x 1 + 16
We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get
22 = 16 x 1 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 698 and 758 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(38,22) = HCF(60,38) = HCF(698,60) = HCF(758,698) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 746 > 2, we apply the division lemma to 746 and 2, to get
746 = 2 x 373 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 746 is 2
Notice that 2 = HCF(746,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 99 > 2, we apply the division lemma to 99 and 2, to get
99 = 2 x 49 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 99 is 1
Notice that 1 = HCF(2,1) = HCF(99,2) .
