Given numbers are 643, 402, 358, 151
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 402) = 258486
GCD(643, 402) = ( 643 x 402 ) / 258486
= 643 / 402
= 643
Step2:
LCM(1, 358) = 358
GCD(1, 358) = ( 1 x 358 ) / 358
= 1 / 358
= 1
Step3:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
So, Greatest Common Divisor of 643, 402, 358, 151 is 1
