Hello I want from lotto draws (for example 100) create a formula ( or another way )which can find 4,5,6,7 … numbers that appears in every draw

For example there are 3 draws , 1 draw =123 2 draw =145 3 draw= 456 the formula must gives these output =145

How can I do it ? Im beggineer may someone writes the formula if it is easy

Or give me councils ? Thanks
