GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 486) = 79218
GCD(978, 486) = ( 978 x 486 ) / 79218
= 978 / 486
= 978
Step2:
LCM(6, 670) = 2010
GCD(6, 670) = ( 6 x 670 ) / 2010
= 6 / 670
= 6
Step3:
LCM(2, 244) = 244
GCD(2, 244) = ( 2 x 244 ) / 244
= 2 / 244
= 2
So, Greatest Common Divisor of 978, 486, 670, 244 is 2
