Given numbers are 290, 649, 674, 653
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 649) = 188210
GCD(290, 649) = ( 290 x 649 ) / 188210
= 290 / 649
= 290
Step2:
LCM(1, 674) = 674
GCD(1, 674) = ( 1 x 674 ) / 674
= 1 / 674
= 1
Step3:
LCM(1, 653) = 653
GCD(1, 653) = ( 1 x 653 ) / 653
= 1 / 653
= 1
So, Greatest Common Divisor of 290, 649, 674, 653 is 1
