GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(802, 630) = 252630
GCD(802, 630) = ( 802 x 630 ) / 252630
= 802 / 630
= 802
Step2:
LCM(2, 578) = 578
GCD(2, 578) = ( 2 x 578 ) / 578
= 2 / 578
= 2
Step3:
LCM(2, 278) = 278
GCD(2, 278) = ( 2 x 278 ) / 278
= 2 / 278
= 2
So, Greatest Common Divisor of 802, 630, 578, 278 is 2
