GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 490) = 490
GCD(245, 490) = ( 245 x 490 ) / 490
= 245 / 490
= 245
Step2:
LCM(245, 535) = 26215
GCD(245, 535) = ( 245 x 535 ) / 26215
= 245 / 535
= 245
Step3:
LCM(5, 791) = 3955
GCD(5, 791) = ( 5 x 791 ) / 3955
= 5 / 791
= 5
So, Greatest Common Divisor of 245, 490, 535, 791 is 1
