GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 970) = 28130
GCD(290, 970) = ( 290 x 970 ) / 28130
= 290 / 970
= 290
Step2:
LCM(10, 476) = 2380
GCD(10, 476) = ( 10 x 476 ) / 2380
= 10 / 476
= 10
Step3:
LCM(2, 728) = 728
GCD(2, 728) = ( 2 x 728 ) / 728
= 2 / 728
= 2
So, Greatest Common Divisor of 290, 970, 476, 728 is 2
