Given numbers are 247, 661, 411, 751

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

Apply this formula for all numbers.

Step1:

LCM(247, 661) = 163267

GCD(247, 661) = ( 247 x 661 ) / 163267

= 247 / 661

= 247

Step2:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

Step3:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1

So, Greatest Common Divisor of 247, 661, 411, 751 is 1
