FORMULA
a(1) = 1, a(n) = lcm(a(n-1), A100778(n)) for n >= 2. - David A. Corneth, Apr 18 2021
EXAMPLE
The least common multiple of the numbers of least prime signature up through 36 is equal to the least common multiple of all primorial powers up through 36, including 2^5 = 32, 6^2 = 36, and 30^1 = 30. Thus 2^5 * 3^2 * 5 = 1440 is a term of this sequence.
