Given numbers are 654, 788, 907, 921

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

Apply this formula for all numbers.

Step1:

LCM(654, 788) = 257676

GCD(654, 788) = ( 654 x 788 ) / 257676

= 654 / 788

= 654

Step2:

LCM(2, 907) = 1814

GCD(2, 907) = ( 2 x 907 ) / 1814

= 2 / 907

= 2

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 654, 788, 907, 921 is 1
