HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 748, 742 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 550, 748, 742 is 2 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 550, 748, 742 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 550, 748, 742 is 2.
HCF(550, 748, 742) = 2
HCF of 550, 748, 742 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 550, 748, 742 is 2.
Highest Common Factor of 550,748,742 is 2
Step 1: Since 748 > 550, we apply the division lemma to 748 and 550, to get
748 = 550 x 1 + 198
Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 198 and 550, to get
550 = 198 x 2 + 154
Step 3: We consider the new divisor 198 and the new remainder 154, and apply the division lemma to get
198 = 154 x 1 + 44
We consider the new divisor 154 and the new remainder 44,and apply the division lemma to get
154 = 44 x 3 + 22
We consider the new divisor 44 and the new remainder 22,and apply the division lemma to get
44 = 22 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 550 and 748 is 22
Notice that 22 = HCF(44,22) = HCF(154,44) = HCF(198,154) = HCF(550,198) = HCF(748,550) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 742 > 22, we apply the division lemma to 742 and 22, to get
742 = 22 x 33 + 16
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 16 and 22, to get
22 = 16 x 1 + 6
Step 3: 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 22 and 742 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(742,22) .
