HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 740, 621 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 740, 621 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 740, 621 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 740, 621 is 1.
HCF(740, 621) = 1
HCF of 740, 621 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 740, 621 is 1.
Highest Common Factor of 740,621 is 1
Step 1: Since 740 > 621, we apply the division lemma to 740 and 621, to get
740 = 621 x 1 + 119
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 119 and 621, to get
621 = 119 x 5 + 26
Step 3: We consider the new divisor 119 and the new remainder 26, and apply the division lemma to get
119 = 26 x 4 + 15
We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get
26 = 15 x 1 + 11
We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get
15 = 11 x 1 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 740 and 621 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(119,26) = HCF(621,119) = HCF(740,621) .
