Given numbers are 453, 210, 514, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(453, 210) = 31710
GCD(453, 210) = ( 453 x 210 ) / 31710
= 453 / 210
= 453
Step2:
LCM(3, 514) = 1542
GCD(3, 514) = ( 3 x 514 ) / 1542
= 3 / 514
= 3
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 453, 210, 514, 780 is 1
