Given numbers are 649, 308, 715, 411

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

Apply this formula for all numbers.

Step1:

LCM(649, 308) = 18172

GCD(649, 308) = ( 649 x 308 ) / 18172

= 649 / 308

= 649

Step2:

LCM(11, 715) = 715

GCD(11, 715) = ( 11 x 715 ) / 715

= 11 / 715

= 11

Step3:

LCM(11, 411) = 4521

GCD(11, 411) = ( 11 x 411 ) / 4521

= 11 / 411

= 11

So, Greatest Common Divisor of 649, 308, 715, 411 is 1
