Given numbers are 801, 642, 247, 372
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 642) = 171414
GCD(801, 642) = ( 801 x 642 ) / 171414
= 801 / 642
= 801
Step2:
LCM(3, 247) = 741
GCD(3, 247) = ( 3 x 247 ) / 741
= 3 / 247
= 3
Step3:
LCM(1, 372) = 372
GCD(1, 372) = ( 1 x 372 ) / 372
= 1 / 372
= 1
So, Greatest Common Divisor of 801, 642, 247, 372 is 1
