Given numbers are 870, 270, 783, 207

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(870, 270) = 7830

GCD(870, 270) = ( 870 x 270 ) / 7830

= 870 / 270

= 870

Step2:

LCM(30, 783) = 7830

GCD(30, 783) = ( 30 x 783 ) / 7830

= 30 / 783

= 30

Step3:

LCM(3, 207) = 207

GCD(3, 207) = ( 3 x 207 ) / 207

= 3 / 207

= 3

So, Greatest Common Divisor of 870, 270, 783, 207 is 3
