HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 990, 836, 702, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 990, 836, 702, 545 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 990, 836, 702, 545 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 990, 836, 702, 545 is 1.
HCF(990, 836, 702, 545) = 1
HCF of 990, 836, 702, 545 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 990, 836, 702, 545 is 1.
Highest Common Factor of 990,836,702,545 is 1
Step 1: Since 990 > 836, we apply the division lemma to 990 and 836, to get
990 = 836 x 1 + 154
Step 2: Since the reminder 836 ≠ 0, we apply division lemma to 154 and 836, to get
836 = 154 x 5 + 66
Step 3: We consider the new divisor 154 and the new remainder 66, and apply the division lemma to get
154 = 66 x 2 + 22
We consider the new divisor 66 and the new remainder 22, and apply the division lemma to get
66 = 22 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 990 and 836 is 22
Notice that 22 = HCF(66,22) = HCF(154,66) = HCF(836,154) = HCF(990,836) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 702 > 22, we apply the division lemma to 702 and 22, to get
702 = 22 x 31 + 20
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 20 and 22, to get
22 = 20 x 1 + 2
Step 3: We consider the new divisor 20 and the new remainder 2, and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 22 and 702 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(702,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 545 > 2, we apply the division lemma to 545 and 2, to get
545 = 2 x 272 + 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 545 is 1
Notice that 1 = HCF(2,1) = HCF(545,2) .
