Given numbers are 200, 970, 249, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(200, 970) = 19400
GCD(200, 970) = ( 200 x 970 ) / 19400
= 200 / 970
= 200
Step2:
LCM(10, 249) = 2490
GCD(10, 249) = ( 10 x 249 ) / 2490
= 10 / 249
= 10
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 200, 970, 249, 621 is 1
