Given numbers are 210, 824, 515, 742
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 824) = 86520
GCD(210, 824) = ( 210 x 824 ) / 86520
= 210 / 824
= 210
Step2:
LCM(2, 515) = 1030
GCD(2, 515) = ( 2 x 515 ) / 1030
= 2 / 515
= 2
Step3:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
So, Greatest Common Divisor of 210, 824, 515, 742 is 1
