Given numbers are 642, 811, 292, 892

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

Apply this formula for all numbers.

Step1:

LCM(642, 811) = 520662

GCD(642, 811) = ( 642 x 811 ) / 520662

= 642 / 811

= 642

Step2:

LCM(1, 292) = 292

GCD(1, 292) = ( 1 x 292 ) / 292

= 1 / 292

= 1

Step3:

LCM(1, 892) = 892

GCD(1, 892) = ( 1 x 892 ) / 892

= 1 / 892

= 1

So, Greatest Common Divisor of 642, 811, 292, 892 is 1
