Given numbers are 648, 218, 946, 785

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(648, 218) = 70632

GCD(648, 218) = ( 648 x 218 ) / 70632

= 648 / 218

= 648

Step2:

LCM(2, 946) = 946

GCD(2, 946) = ( 2 x 946 ) / 946

= 2 / 946

= 2

Step3:

LCM(2, 785) = 1570

GCD(2, 785) = ( 2 x 785 ) / 1570

= 2 / 785

= 2

So, Greatest Common Divisor of 648, 218, 946, 785 is 1
