Given numbers are 287, 672, 434, 572
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 672) = 27552
GCD(287, 672) = ( 287 x 672 ) / 27552
= 287 / 672
= 287
Step2:
LCM(7, 434) = 434
GCD(7, 434) = ( 7 x 434 ) / 434
= 7 / 434
= 7
Step3:
LCM(7, 572) = 4004
GCD(7, 572) = ( 7 x 572 ) / 4004
= 7 / 572
= 7
So, Greatest Common Divisor of 287, 672, 434, 572 is 1
