Given numbers are 210, 915, 425, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 915) = 12810
GCD(210, 915) = ( 210 x 915 ) / 12810
= 210 / 915
= 210
Step2:
LCM(15, 425) = 1275
GCD(15, 425) = ( 15 x 425 ) / 1275
= 15 / 425
= 15
Step3:
LCM(5, 121) = 605
GCD(5, 121) = ( 5 x 121 ) / 605
= 5 / 121
= 5
So, Greatest Common Divisor of 210, 915, 425, 121 is 1
