HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 528, 870, 621 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 528, 870, 621 is 3 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 528, 870, 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 528, 870, 621 is 3.
HCF(528, 870, 621) = 3
HCF of 528, 870, 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 528, 870, 621 is 3.
Highest Common Factor of 528,870,621 is 3
Step 1: Since 870 > 528, we apply the division lemma to 870 and 528, to get
870 = 528 x 1 + 342
Step 2: Since the reminder 528 ≠ 0, we apply division lemma to 342 and 528, to get
528 = 342 x 1 + 186
Step 3: We consider the new divisor 342 and the new remainder 186, and apply the division lemma to get
342 = 186 x 1 + 156
We consider the new divisor 186 and the new remainder 156,and apply the division lemma to get
186 = 156 x 1 + 30
We consider the new divisor 156 and the new remainder 30,and apply the division lemma to get
156 = 30 x 5 + 6
We consider the new divisor 30 and the new remainder 6,and apply the division lemma to get
30 = 6 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 528 and 870 is 6
Notice that 6 = HCF(30,6) = HCF(156,30) = HCF(186,156) = HCF(342,186) = HCF(528,342) = HCF(870,528) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 621 > 6, we apply the division lemma to 621 and 6, to get
621 = 6 x 103 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 621 is 3
Notice that 3 = HCF(6,3) = HCF(621,6) .
