HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 748, 550 i.e. 22 the largest integer that leaves a remainder zero for all numbers.
HCF of 748, 550 is 22 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 748, 550 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 748, 550 is 22.
HCF(748, 550) = 22
HCF of 748, 550 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 748, 550 is 22.
Highest Common Factor of 748,550 is 22
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 748 and 550 is 22
Notice that 22 = HCF(44,22) = HCF(154,44) = HCF(198,154) = HCF(550,198) = HCF(748,550) .
