Given numbers are 661, 920, 453, 801

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

Apply this formula for all numbers.

Step1:

LCM(661, 920) = 608120

GCD(661, 920) = ( 661 x 920 ) / 608120

= 661 / 920

= 661

Step2:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

Step3:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

So, Greatest Common Divisor of 661, 920, 453, 801 is 1
