Given numbers are 698, 261, 650, 921

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

Apply this formula for all numbers.

Step1:

LCM(698, 261) = 182178

GCD(698, 261) = ( 698 x 261 ) / 182178

= 698 / 261

= 698

Step2:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

Step3:

LCM(1, 921) = 921

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

= 1 / 921

= 1

So, Greatest Common Divisor of 698, 261, 650, 921 is 1
