Given numbers are 647, 661, 249, 152

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

Apply this formula for all numbers.

Step1:

LCM(647, 661) = 427667

GCD(647, 661) = ( 647 x 661 ) / 427667

= 647 / 661

= 647

Step2:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

Step3:

LCM(1, 152) = 152

GCD(1, 152) = ( 1 x 152 ) / 152

= 1 / 152

= 1

So, Greatest Common Divisor of 647, 661, 249, 152 is 1
