Given numbers are 840, 519, 487, 474
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 519) = 145320
GCD(840, 519) = ( 840 x 519 ) / 145320
= 840 / 519
= 840
Step2:
LCM(3, 487) = 1461
GCD(3, 487) = ( 3 x 487 ) / 1461
= 3 / 487
= 3
Step3:
LCM(1, 474) = 474
GCD(1, 474) = ( 1 x 474 ) / 474
= 1 / 474
= 1
So, Greatest Common Divisor of 840, 519, 487, 474 is 1
