Given numbers are 465, 840, 434, 987

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

Apply this formula for all numbers.

Step1:

LCM(465, 840) = 26040

GCD(465, 840) = ( 465 x 840 ) / 26040

= 465 / 840

= 465

Step2:

LCM(15, 434) = 6510

GCD(15, 434) = ( 15 x 434 ) / 6510

= 15 / 434

= 15

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 465, 840, 434, 987 is 1
