Given numbers are 998, 690, 885, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 690) = 344310
GCD(998, 690) = ( 998 x 690 ) / 344310
= 998 / 690
= 998
Step2:
LCM(2, 885) = 1770
GCD(2, 885) = ( 2 x 885 ) / 1770
= 2 / 885
= 2
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 998, 690, 885, 445 is 1
