Given numbers are 710, 840, 503, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(710, 840) = 59640
GCD(710, 840) = ( 710 x 840 ) / 59640
= 710 / 840
= 710
Step2:
LCM(10, 503) = 5030
GCD(10, 503) = ( 10 x 503 ) / 5030
= 10 / 503
= 10
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 710, 840, 503, 490 is 1
