Given numbers are 990, 722, 245, 175
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 722) = 357390
GCD(990, 722) = ( 990 x 722 ) / 357390
= 990 / 722
= 990
Step2:
LCM(2, 245) = 490
GCD(2, 245) = ( 2 x 245 ) / 490
= 2 / 245
= 2
Step3:
LCM(1, 175) = 175
GCD(1, 175) = ( 1 x 175 ) / 175
= 1 / 175
= 1
So, Greatest Common Divisor of 990, 722, 245, 175 is 1
