HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 536, 621 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 536, 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 434, 536, 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 434, 536, 621 is 1.
HCF(434, 536, 621) = 1
HCF of 434, 536, 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 434, 536, 621 is 1.
Highest Common Factor of 434,536,621 is 1
Step 1: Since 536 > 434, we apply the division lemma to 536 and 434, to get
536 = 434 x 1 + 102
Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 102 and 434, to get
434 = 102 x 4 + 26
Step 3: We consider the new divisor 102 and the new remainder 26, and apply the division lemma to get
102 = 26 x 3 + 24
We consider the new divisor 26 and the new remainder 24,and apply the division lemma to get
26 = 24 x 1 + 2
We consider the new divisor 24 and the new remainder 2,and apply the division lemma to get
24 = 2 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 434 and 536 is 2
Notice that 2 = HCF(24,2) = HCF(26,24) = HCF(102,26) = HCF(434,102) = HCF(536,434) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 621 > 2, we apply the division lemma to 621 and 2, to get
621 = 2 x 310 + 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 621 is 1
Notice that 1 = HCF(2,1) = HCF(621,2) .
