Given numbers are 490, 635, 628, 270
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 635) = 62230
GCD(490, 635) = ( 490 x 635 ) / 62230
= 490 / 635
= 490
Step2:
LCM(5, 628) = 3140
GCD(5, 628) = ( 5 x 628 ) / 3140
= 5 / 628
= 5
Step3:
LCM(1, 270) = 270
GCD(1, 270) = ( 1 x 270 ) / 270
= 1 / 270
= 1
So, Greatest Common Divisor of 490, 635, 628, 270 is 1
