Given numbers are 649, 181, 324, 715

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

Apply this formula for all numbers.

Step1:

LCM(649, 181) = 117469

GCD(649, 181) = ( 649 x 181 ) / 117469

= 649 / 181

= 649

Step2:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 649, 181, 324, 715 is 1
