Given numbers are 649, 989, 262, 545

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

Apply this formula for all numbers.

Step1:

LCM(649, 989) = 641861

GCD(649, 989) = ( 649 x 989 ) / 641861

= 649 / 989

= 649

Step2:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 649, 989, 262, 545 is 1
