Given numbers are 722, 490, 219, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(722, 490) = 176890
GCD(722, 490) = ( 722 x 490 ) / 176890
= 722 / 490
= 722
Step2:
LCM(2, 219) = 438
GCD(2, 219) = ( 2 x 219 ) / 438
= 2 / 219
= 2
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 722, 490, 219, 447 is 1
