Once you find the prime factorization, every factor is contained there.
2 x 2 x 5 x 7 x 11 = 1540 Remember to include 1.
1,2,5,7,11
4,10,14,22 (2x2, 2x5, 2x7, 2x11)
20,28 (2x2x5, 2x2x7)
35 (5x7)
That's half of them. The other half can be found by dividing this half into 1540.
1, 2, 4, 5, 7, 10, 11, 14, 20, 22, 28, 35, 44, 55, 70, 77, 110, 140, 154, 220, 308, 385, 770, 1540
What are the greatest common factors of 990 and 1540
1,2,4,5,7,10,11,14,20,22,28,35,44,55,70,77,110,140,154,220,308,385,770,1540
2^2x5x7x11
770, 1540, 2310, 3080, 3850 . . .
7*220=1540
1540 = 2 x 2 x 5 x 7 x 11 All of its prime factors are not even in quantity, hence it's not a perfect square number. PS You could've used a calculator instead.
1540 yards = 0.875 miles
The king is Carlos I and the queen is Amelie
1540 AD is the sixteenth century.
1, 2, 4, 5, 7, 10, 11, 14, 20, 22, 28, 35, 44, 55, 70, 77, 110, 140, 154, 220, 308, 385, 770, 1540 -1, -2, -4, -5, -7, -10, -11, -14, -20, -22, -28, -35, -44, -55, -70, -77, -110, -140, -154, -220, -308, -385, -770, -1540
There are 1760 yards in one mile. Therefore, 1540 yards is equal to 1540/1760 = 0.875 miles.
The GCF is 35.
